To square any number which is between 25-50.say 46.say 46-25(the lower range)=21.then say 50(the higher range)-46=4 and square the four to give 16.take the two together to get 2116...let's try that of 48.you say 48-25=23.then 50-48=02 and square it to give 04.take it together to get 2304 J.Rika:... 1 Like |

To multiply any number by 5,50,500 etc...let's use a manipulation as this...5=10/2.so assuming you want to multiply 448 by 5.just divide 448 by 2 and add a nought...therefore 448/2=224.then add a nought to give 2240.assuming you want to multiply 363 by 50...divide 363 by 2 and add 2 noughts.363/2=181.5 and add 2 noughts to give 18150... |

Pls.nairalanders.i want you to post more of this...if you don't know any...just type your comment to impress those that are typing it...there are still many more of these...i still lay emphasis on square,if you show that you like this thread...i will post multiplication to the extent that you can go to the examination hall without calculator...also need a magic to know trig. Functions sin and cos offhand.just comment on this thread... 2 Likes |

Nice one bro. . . .keep it up! |
Re: How To Calculate Quickly And Correctly In Mathematics by Calculusfx: 8:42pm On Jun 16, 2013 |
To know if a number is divisible by 9...just add the numbers together,if it's a multiple of 9.then 9 will surely go in it...e.g.747...you say 7+4+7=18...18 is a multiple of 9...then 9 is a factor of 747...what about 735...add the numbers 7+3+5=15...15 is not a multiple of 9...therefore 9 is not a factor of 735.THE SAME RULE APPLY FOR 3...THEREFORE 735 IS A MULTIPLE OF 3 BECAUSE 15 IS A MULTIPLE OF 3 |

Calculusf(x): Does this also apply to all numbers? |

Hi, pls can u teach me how to multiply numbers in different bases apart from base 10? I really need it. |
Re: How To Calculate Quickly And Correctly In Mathematics by Calculusfx: 10:31am On Jun 18, 2013 |
Omosivie,:...base 10...is generally use by everyone...but when i get any trick for any other base,i will let you know |
Re: How To Calculate Quickly And Correctly In Mathematics by Ortarico(m): 10:35am On Jun 18, 2013 |
Calculusf(x): All right Prof |
Re: How To Calculate Quickly And Correctly In Mathematics by Omosivie1(f): 11:41am On Jun 18, 2013 |
Calculusf(x):Ok, thanks. Can u pls help me out with this question: Simplify log 25^x(base 5) - log0.04(base 5). |
Re: How To Calculate Quickly And Correctly In Mathematics by Ortarico(m): 12:27pm On Jun 18, 2013 |
Omosivie,: Lemme help you.... Log_{5}25^{x} - log_{5} log_{5}5^{2(x)} - log_{5}(4/100) 2xlog_{5}5 - log_{5}(1/25) 2x*1 - (log_{5}5/log_{5}5^{2} 2x - 1/2 = 0 2x = 1/2 x = 1/4 1 Like |
Re: How To Calculate Quickly And Correctly In Mathematics by Omosivie1(f): 1:01pm On Jun 18, 2013 |
Ortarico:Thanks, but ur answer is not among the options. The options are: A 2x+1 B 2x+2 C x/2 D 2x-2. I hope u can understand my workings cos i don't know how to use subscript and superscrpit on nairaland cos i'm on mobile. Log25^x(base 5) - log 4/100(base 5) log5^2x(base 5) - log 5^-2(base 5) NB: log5(base 5) = 1. 2x-(-2) 2x+2. My final answer is 2x+2 but the textbook says it's 2x-2. Can u pls point out my mistake? 1 Like |
Re: How To Calculate Quickly And Correctly In Mathematics by Calculusfx: 2:47pm On Jun 18, 2013 |
Omosivie,:...you are very right bro with what you did,i can't say the textbook is wrong,maybe it's typographical error,i mean the answer the textbook provided but your answer is right... |
Re: How To Calculate Quickly And Correctly In Mathematics by Ortarico(m): 3:02pm On Jun 18, 2013 |
Omosivie,: Yes you're right, cause with the options it's easier to work out what/how the examiner wants the equation to be. |
