Step 3 is where the first mistake occurs

Hey there!

The mistake occurs in [tex]3^{rd}[/tex] step.

Explanation:

As in [tex]3^{rd}[/tex] step we can easily notice that 8 + 2 gives 10,but here it's written 4. For which the answer came invalid.

So the answer will be:

Step 1: 8 + 2 + (3 × 1)

Step 2: 8 + 2 + 3

Step 3: 10 + 3 [ corrected]

Step 4: 13

Hope it helps
