Parisian:I forgot to add Bosnia and Herzegovina, and Faroe Island. Almighty Ronaldo will get there with more friendlies involving any of these teams. |
With enough Lithuania, Estonia, Macedonia, Luxembourg, Andorra, Latvia, Armenia and the likes, he will get there. ![]() |
BluntNigerian:For your question 6 ÷ 2(2 +1), you need to have it in mind that grouping symbols imply multiplication as I pointed out. 6 ÷ 2(2 + 1) = 6 ÷ 2 × (2 + 1) = 6 ÷ 2 × 3 STEP 1 = 3 × 3 = 9 STEP 3 (there are no roots and exponents so we moved on to step 3). If 2(2 + 1) was the denominator of your question, the right expression would have been 6 ÷ (2(2 + 1)). You answer here would have been 1. As to your question, 20 ÷ 5(2x + 3) = 5. You treat the expression in the brackets as a single number, say y. So let's say 2x + 3 = y. 20 ÷ 5(2x + 3) = 20 ÷ 5(y) = 20 ÷ 5 × y 20 ÷ 5 × y = 4 × y STEP 3 4 × y = 4y = 4(2x + 3) 4(2x + 3) = 8x + 12 (distributive property.) 8x + 12 = 5 8x = 5 - 12 = –7 x = –7 ÷ 8 = –(7/8 ) I actually don't know what you are driving at with the solution to an algebraic equation in one variable. |
lalabrother:I hate cowards that beat about the bush. Just go straight to the point and say you FEEL the wife is innocent of the accusation. |
The ruling is unfair. Equality, not equity, should be embraced in sports. |
aysnoopy:6 ÷ 2 × (x + 1) = 9 3 × (x + 1) = 3(x + 1) = 9 From here, you can divide both sides by 3 and solve for x, or you could distribute 3 over (x + 1) first and then solve for x. Let's try the first step and second step. STEP 1: 3(x + 1) = 9 (x + 1) = x + 1 = 9 ÷ 3 = 3 x + 1 = 3 x = 3 – 1 = 2 STEP 2: 3(x + 1) = 9 3x + 3 = 9 3x = 9 – 3 = 6 3x = 6 x = 6 ÷ 3 = 2 |
SkyFlint:I actually know men like this. They think not all women are like that and they can procure the "happily ever after" with their NAWALTs in an alpha/red pill way. It will always end in tears. ![]() |
aysnoopy:6 ÷ 2 × (2 + 1) = 6 ÷ 2(2 + 1) OLODO RABATA! ![]() I just created a thread for you. https://www.nairaland.com/6106491/basic-arithmetic-response-bluntnigerians-thread |
▪︎If a grouping symbol is "attached" to a number or another grouping symbol, multiplication is implied. For example 2(3 + 4) means 2 × (3 + 4) (3 ÷ 5)(5 – 1) means (3 ÷ 5) × (5 – 1) [4² + 3](4 × 7) means [4² + 3] × (4 × 7) {3 + 3 ÷ 3}[2 ÷ 4][4 × 7] means {3 + 3 ÷ 3} × [2 ÷ 4] × [4 × 7] This applies to all grouping symbols and any possible combination of them. |
No matter what your teachers thought you in primary or secondary school, if your workings defy this set of rules and you don't get the answer determined by them, you have failed by the standard of Mathematics. GROUPING SYMBOLS. Grouping symbols determine the order in which an arithmetic expression is to be evaluated. Group symbols are: (1) Parentheses ( ). "Parentheses" is North American English. In British English, and consequently in this country, parentheses are simply called brackets or round brackets. (2) Brackets [ ]. In British English, this is referred to as square bracket. (3) Braces { }. Most of us who studied Set should be familiar with braces. Braces are also grouping symbols in arithmetic. (4) Fraction bar – . The fraction bar is used when we write fractions. The numerator stays on top of the bar while the denominator stays below.If a fraction bar occurs in an arithmetic expression, you "clear it" as the grouping symbol that it is by evaluating its numerator and denominator following STEP 2 - 4 in order, and then you divide. Remember you must first evaluate all expressions in grouping symbols working from inside to outside. If you don't understand, tell me and I will explain in detail. |
Recently, a nairalander BluntNigerian tabled a problem involving basic arithmetic which confounded him in this thread of his. His problem was that he obtained 9 and 1 as answers to 6 ÷ 2(2 + 1) from his android calculator and calcio calculator respectively. In his opinion, the makers of android ought to be sued. One would have thought the many maths literate in this section would have educated him on this issue and pointed out the correct answer to him but things took a shocking turn. Some people said 9 and 1 are both correct, and some people agreed with them. More shocking was a supposed Engineer and Physics teacher agreeing with this. Some even said 1 is the correct answer. In this thread of mine, I will like to educate the readers on the order of arithmetic operations. ![]() When solving an arithmetic problem, there is a conventional set of rules one must adhere to in obtaining an answer. This conventional set of rules eliminates any ambiguity an arithmetic expression could possibly present. For example, how do you solve 6 + 2 × 3? Do you add first or multiply first? What is the difference between 6 ÷ (2(2 + 1)) and 6 ÷ 2(2 + 1)? As you would see, the conventional set of rules which is called ORDER OF ARITHMETIC OPERATIONS will help us answer these questions. This set of rules is the standard; this means there can't be two answers to an arithmetic expression. There can be one and only one answer. ORDER OF ARITHMETIC OPERATIONS ![]() This lists out the order you must take in solving an arithmetic expression. The order is as follows: STEP 1: perform all calculations within grouping symbols following the order listed from STEP 2 - 4, working from the innermost pair of grouping symbols to the outermost pair. Group symbols are parentheses, square brackets, braces, and fraction bars. I will later explain grouping symbols in details. STEP 2: evaluate all exponential expressions and roots. STEP 3: perform all operations of multiplication and division as they occur from left to right. STEP 4: perform all operations of addition and subtraction as they occur from left to right.

aysnoopy:Shut your dirty mouth. ![]() When you use slash, the you have fraction whose numerator is 6 and whose denominator is 2(2 + 1). X/Y = X ÷ Y 6/2(2 + 1) = 6 ÷ [2(2 + 1)] 6 ÷ [2(2 + 1)] is different from 6 ÷ 2(2 + 1). One has two grouping symbols (brackets) while the other has just one. When you solve the expression in the grouping symbols of both expressions from inside to outside, which is what you must always do first, you get 6/6 or 6 ÷ 6 for the first expression and you get 6 ÷ 2 × 3 for the second expression. OLODO RABATA. SHAME! SHAME! |

aysnoopy:Olodo. You don't even know the answer to a simple arithmetic problem. Even my junior sister won't fail that question in the OP. ![]() |
aysnoopy:Your ignorance is a confident one. You gave me an algebraic expression in one variable to solve and you want to compare it to solving a simple arithmetic problem? Let me school you. When given the problem 6 ÷ 2(2 + 1), the first thing to do is evaluate what's in the grouping symbol(s) (in this case, a bracket) for inward to outward. Finally you solve the divisions and multiplications as they occur from left to right. The answer to the question is 9. Because of ignorant fools like you, I will create a topic explaining the principles of arithmetic operations. Waste of school fees, waste of certificate. OLODO RABATA. |
aysnoopy:1 + 5(2x + 3) = 5 1 + (10x + 15) = 5 10x + 15 = 4 10x = -11 x = -1.1 It's a pity that many educated people like you, I presume, don't understand the principles of basic arithmetic. Shame! Big shame! |

Goldeno: Seikiri1:❌❌❌❌❌❌❌❌❌❌❌❌❌❌❌ The correct answer is 9. 1 is wrong. |
The android calculator is correct. You probably need to change the battery of your calcio calculator. |
Kiddwaya na better person. |
This is good stuff. Ride on! |
Rollercoaster relationship. |
ReeLoaDead:That's how he is. No religious folks can provide proof of their god's existence; there is no such proof since God is nonexistent. They can't validate the claims of their holy books. Everything is by faith and lies. If faith is justifiable evidence, when can't I believe in a pink, indestructible, immortal, and eternally hibernating unicorn in the centre of planet pluto. Though I can't prove it but I have faith that it exists. I dare you to profess your doubt of this in public and see if you will not be shown it's existence and given a brain reset. Lol. ![]()

ReeLoaDead:Some people are fools by choice, some are apparent result of their genetics. I think eni4reál might belong to the latter. It's not easy to tell with certainty since most Barça fans had their sanity compromised when Bayern hammered them. ![]() |
eni4real: lol. Funny how you can't make a reasonable and compelling case for your god's existence and claims of your holy book, instead you are daring me to go offline as if a brutal and hostile retaliation will prove god's existence to me. What a coward! Why resort to passive threat? Grow some balls and make a logical and reasonable case for your God's existence. Anyway, let me break it to you... no one can do that, not even you. ![]() The so-called radical muslims and core Islamic countries have threatened, terrorized and punished those who dare speak against their holy book and prophet and are culpable for apostasy. Did it prove the existence of Allah and validate the Quran? Hell no! Christians burnt thousands of alleged heretics on the stacks, yet atheism wasn't obliterated. Oga, you are just fooling yourself. Odeshi and juju supposedly exist yet our ancestors were taken as slaves and our military can't use them to fortify themselves and rule over nations. Tueh! Blood money, blood money, yet Nigeria is one of the poverty hotspots of planet earth. Good day. I leave you to rot in your self-deception and dishonesty. ![]() |
eni4real:Who do you intend as "they"? What do you mean by "make god real"? All you need is a 'real life' resetting!!What do you mean by "real life" resetting? What is "real life" resetting? Your online depositions are mere Trolling!!Blah blah blah. Funny how you can't make a logical and cogent case for your god online even if your life depended on it. Just like the religiotard I presumed you to be, you had to barricade yourself in aggression, strawmen and a passive threat of getting a hostile and brutal retaliation if profess my unbelief in public. You CANNOT defend your religious beliefs. No wonder no one takes a god who was, and still is, humbled by the coronavirus seriously. ![]() |
