1. 23 x 50
20 x 50 = 1000
3 x 50 = 150
1000 + 150 = 1150

2. 30 x 82
30 x 80 = 2400
30 x 2 = 60
2400 + 60 = 2460

Answer 2

Answer:

For the first one, it is 1150. For the second one, it is 2460.

Step-by-step explanation:

Think of 23 x 50 as (20 x 50) + (3 x 50).

20 x 50 is 1000. 3 x 50 is 150. 1000 + 150 is 1150.

Think of 30 x 82 as (30 x 80) + (30 x 2)

30 x 80 is 2400. 30 x 2 is 60. 2400+60 is 2460.
