Question

Giving up al my point for this question

Answer 1

the mistake is PEMDAS is not being used, the correct way to solve this would be the multiply 4x9 then add 1. The correct answer is 37!

Answer 2

The mistake there is the expression shown is not in PEMDAS.

PEMDAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents(degree or square roots) and later we do operations on multiplication & division and at last addition and subtraction.

Explanation:

1 + 4 x 9 4 x 9 = 36

1 + 36 36 + 1 = 37

37

Always remeber to use multiplication first!
