Question

Find the value of 7 + 32 (-5 + 1) ÷ 2.

25
32
-11

Answer 1

−57

Answer 2

7 +32( -5 +1) /2
Remember your order of operations. We do parentheses first:

7 +32( -4) /2
Now, multiplication and division together:
7 + 32*-4 /2
7 -128 /2
7 -64
Now, subtraction.
-57

Answer 3

Order of operations,

First the parenthesis, -5 + 1 = -4

7 + 32(-4)/2

Multiplication then division,

7 -128/2

-128/2 = -64

7 + (-64) = -57

Answer 4

oh sorry guys its not 32, its 3^2 (2 as an exponent)

Answer 5

7 +3^2( -5 +1) /2
We still do parentheses first:
7 +3^2(-4) /2
Next, exponents:
7 +9(-4) /2
Now, multiplication and division together (whichever comes first, left to right):
7 -36 /2
7 -18
Finally, addition and subtraction together (whichever comes first, left to right):
-11

Answer 6

Oh,

7 + 3^2 (-5 + 1) ÷ 2.

7 + 3^2 * -4/2

7 + 9 * -2

7 -18 = 11

Answer 7

thank you guys!!

Answer 8

-11, 7 is smaller than 18
