Question

Two students wrote the following numerical expressions.
Angeline: (7 + 15) × (38 + 15)
MeiLing: 15 × (7 + 38)
Are the students’ expressions equivalent to your answer in Problem 4? Explain your answer.

Answer 1

Answer:

The expression are not equivalent.

Step-by-step explanation:

For Angeline we have the next process:

$(7+15)\times(38+15)=22\times53=1166$

For MeiLing we have:

$15\times(7+38)=15\times45=675$

Then we have that the students expressions are not equivalent.

The process to solver the expressions was solving first the parenthesis and after that solver the multiplication.
