Isabel tried to evaluate an expression step by step. \quad\begin{aligned} &(2+8)+8 \\ =&2+(8+8)&\green{\text{Step } 1} \\ \\ =&2+0&\blue{\text{Step } 2} \\ \\ =&2&\purple{\text{Step } 3} \\ \\ \end{aligned}

(2+8)+8
2+(8+8)
2+0
2


Step 1
Step 2
Step 3


Find Isabel's mistake.

Step three

Step-by-step explanation:

(2+8)+8

2+(8+8)    

2+0

2

In the third step Isabel subtracted 8 into 8 not added, in order to evaluate the expression correctly she needed to add 8 into 8 and then add the two.

Hope this helps.
