1. A) Division using Repeated Subtraction
Example: Solve 12 ÷ 2 using repeated subtraction
Method: Take away by 2 until it gets zero result.
12 – 2 = 10
10 – 2 = 8
8 – 2 = 6
6 – 2 = 4
4 – 2 = 2
2 – 2 = 0
Therefore, 12 ÷ 2 = 6
B) How the calculator skip reading and counting?
For example, key in 12 – 6 on the calculator then press “=”
continuously until it displays zero result.
Count how many times it is subtracted by 2?
Answer: There are six 2s.
