Question

Two students Kendra and Laura solved the following expression: |4 - 7| + 2 * 5 . Kendra got a final answer of 13 and Laura got an answer of 7. Who got the answer WRONG and HOW do you know. (The how should refer to the math being done. You can NOT say because I solved it. I need a description)

Answer 1

|4 - 7| = |-3| = 3

|z| is interpreted as the absolute value of z, which is the distance from 0 to z.

|4 - 7| + 5*2 = 3 + 10 = 13.

Laura got the answer wrong.
