Question

Hayden evaluated this expression using the order of operations, but he made a mistake. Which step includes Hayden's mistake?

-6 + 8(11 – 4) + 32
Step 1
= -6 + 8(7) + 32
Step 2
= -6 + 8(7) +9
Step 3
= 2(7) +9
Step 4
= 14 + 9
Step 5
= 23

Answer 1

9514 1404 393

Answer:

step 3

Explanation:

The multiplication indicated in step 2 should be carried out to get to step 3.

= -6 +56 +9 . . . correct step 3

Then, step 4 is ...

= 50 +9

and step 5 is ...

= 59

Hayden's mistake is in step 3 where he ignores the order of operations requirement to perform multiplication before addition.
