# what do you think the true answer to this question is as there are no arithmetic signs at the end of the first 2 rows

Assuming this is one question:

1+1+1+1+1+1+1+1+1+1+1+1x0+1=?

The correct answer is 12 -- first do the multiplication, then add the remaining 12 ones to get 12.

The key is to use order of operations. First take care of any grouping symbols (parentheses, brackets, braces, absolute value, etc...), the multiplication and division from left to right and then addition or subtraction from left to right.

The common mistake will be to add sequentially the first 11 ones then multiply by zero (getting zero) and then adding one to get 1 as an answer.

The precedence of operators has to be kept in mind when determining the result in these questions. a simple mnemonic for this is BODMAS, first complete operations within brackets, then take care of exponents followed by division, multiplication, addition and subtraction.

For the problems you have mentioned:

1+1+1+1+1

Just start from the left and proceed to the right

2+1+1+1

= 3+1+1

= 4+1

= 5

1+1 x 0+1

Here, take care of the multiplication first, 1 x 0 = 0

= 1 + 0 + 1

= 1 + 1

= 2

I'd assume that whoever created this problem probably forgot to add the operators at the end. One interpretation of this question is as follows:

1+1+1+1+1+1+1+1+1+1+1+1*0+1=?

BEDMAS is an acronym that describes the order of operations. In our problem here, we only have 2 operations - multiplication and addition.

According to BEDMAS, we do the multiplication first. So, this:

1+1+1+1+1+1+1+1+1+1+1+1*0+1=?

Is really this:

1+1+1+1+1+1+1+1+1+1+1+(1*0)+1=?

So, we do the 1*0 independently, which is 0:

1+1+1+1+1+1+1+1+1+1+1+(0)+1=?

We can then add up all the integers, and get the result of 12.
