Mathematics

- 1.Choose a 2-digit number.

2.Select a number either 3 smaller or 3 larger.

3.Add 1 to the smaller number, then square.

4.Subtract one from the smaller number.

5.Add this to the square.

- 1.If the first number is 63, choose 67 as the second number.

2.The middle number (the average) is 65.

3.Square this middle number: 65 x 65 = 4225. Remember how to square a 2-digit number ending in 5?

4.Subtract 4 from this square: 4225 - 4 = 4221.

5.So 63 x67 = 4221.

- 1.If the first number is 38, choose 42 as the second number.

2.The middle number (the average) is 40.

3.Square this middle number: 40 x 40 = 1600.

4.Subtract 4 from this square: 1600 - 4 = 1596.

5.So 38 x 42 = 1596.
