A few sample questions
1. What is 25 × 4?
Answer: 100
25 × 4 = 100. A quick trick: 25 × 4 is the same as 100, since four quarters make a dollar.
2. What is 150 ÷ 6?
Answer: 25
150 ÷ 6 = 25. You can break this down: 120 ÷ 6 = 20, and 30 ÷ 6 = 5, so 20 + 5 = 25.

Answer: 60
18 + 27 + 15 = 60. A helpful trick: 18 + 27 = 45, then 45 + 15 = 60.
