Answer:

No, she made mistake from step 3, going to step 4

Step-by-step explanation:

See attachment for complete expression and Tisha's steps

Required

Is she correct?

The steps up to step 3 is correct.

However, going to step 4; she made a mistake

Her expression is:

Step 3: 90 - 2 * 3

The correct step is to multiply 2 by 3 (using BODMAS)

This will give:

90 - 6

84

But instead she evaluated the subtraction first, which is incorrect.
