16. $100 - 3^2 × 4^2$

Explanation:

Let's solve each problem step by step:

1. \(7 - 6 + 5\)

Step 1: Subtract 6 from 7

\(7 - 6 = 1\)

Step 2: Add 5 to the result

\(1 + 5 = 6\)

Answer:

6

2. \(11 + 19 - 8\)

Step 1: Add 11 and 19

\(11 + 19 = 30\)

Step 2: Subtract 8 from the result

\(30 - 8 = 22\)
