Let’s solve each multiplication problem step by step.
We’re multiplying whole numbers by multiples of 10 (like 10, 20, 30, etc.).
A quick way: multiply the first number by the non-zero digit, then add a zero at the end.
Example:
7 × 80 → 7 × 8 = 56 → add a zero → 560
Let’s go row by row:

8 × 10 = 80
5 × 70 = 350
4 × 80 = 320

Second column:
5 × 10 = 50
1 × 50 = 50
4 × 40 = 160
9 × 40 = 360
8 × 60 = 480
4 × 50 = 200
6 × 40 = 240
7 × 60 = 420

Third column:
7 × 90 = 630
9 × 20 = 180
3 × 50 = 150
6 × 70 = 420
6 × 60 = 360
4 × 40 = 160
6 × 30 = 180
