Question

PLEASE HELP WITH THIS QUESTION!!!!! /:

Danny made a mistake in the following problem.

The mistake was made in Line ___. Only input the number of the first incorrect line.

Line 1 --- 21 + 35 ÷ 7 + 6(2)

Line 2 --- 21 + 5 + 6(2)

Line 3 --- 21 + 11(2)

Line 4 --- 21 + 22

Line 5 --- 43

Answer 1

The order of operations is: PEDMAS
P - Parenthesis (that is, do the arithmetic within the parenthesis first)
E - Exponent
D & M - Division and Multiplication (both operations same priority)
A & S - Addition and Subtraction (both operations same priority)

In one of the lined an addition operation was performed BEFORE multiplication and that is where the first error occurs.

Answer 2

So line 2? @ranga

Answer 3

Line 2 is correct. It is from Line 1 where the division operation was performed correctly which results in line 2.

Answer 4

I am not saying line 2 is the correct answer. I am saying line 2 has no error.

Answer 5

Going from line 2 to line 3, the operation that should be performed is the multiplication:
6(2) = 12. But instead, the error in line 3, is adding 5 + 6 in line 2 instead of multiplying 6 and 2 first.

Answer 6

Oh ok, thank you so much! I get it now. I'm terrible at math. ): @ranga
