Simple BODMAS... Eliminate multiplication before the simple arithmetics.

10*0=0
20+20=40
5+5=10
0+40+10=50
QED

Modify :

No, the answer can't be 50 because we cannot just ignore the - sign we got from multiplying -10*0

So, this problem cannot be solved mathematically because you cannot multiply a number by a negative number
I agreed with you on the fact that we cannot ignore the negative sign, but the question can be solved mathematically

Your BODMAS calcution is wrong. You will solve the 2 addition before the subtraction. Subtraction comes last in BODMAS

Yes but also the multiplication comes before the addition.

Apply bodmas.multiplication first.which is -10*0%=0 20+20+5+5=50
Exactly, anything multiply by zero is zero.
Re: Can You Solve This Without Calculator? by noble99: 3:01pm On Dec 31, 2020
The answer is 10. 20+20=40-10=20*0=0+5+5=10

What will I gain after solving it?
Although I have solved many math problems before, I have never earned up to 13000naira as a Mathematician.
What is the essence?

You should have restricted participants to certain grade level. This should be for pupils in primary school. Even basic 4 students should be able to answer this question.

I do not agree that a number cannot be multiplied by a negative number.

For example, if you were to do this : -2 x -7, would you say there is no solution to this?

In this case, one only needs to carry out the multiplication operation in two parts

1. between the respective signs of the operands

2. between the absolute values of the operands.

When I say absolute values, I mean using them in natural form(as positive numbers).

The absolute values of -2 and -7 are 2 and 7 respectively.

now we do this:

- x - = +

2 x 7 = 14


Putting the two together, we have +14 or simply 14

Thanks bro, I don't know why majority are saying 50


But, remember, any number multiplied by 0 will still give u zero, no matter the sign
