Find four pairs of number ,one for each of addition ,subtraction, multiplication, division that make the number 18. Write the equalities for each of them.
Solution:
9 + 9 = 18
20 - 2 = 18
9 × 2 = 18
36 ÷ 2 = 18
So, (9 + 9) = (20 - 2) = (9 × 2) = (36 ÷ 2)
Given : Two numbers make the number 18 with addition ,subtraction, multiplication, division
To find : Pair of Numbers
Solution:
Pair of numbers
A B
A + B = 18
A - B = 18
A * B = 18
A / B = 18
A + B = 18
A B
1 17 1 + 17 = 18
2 16 2 + 16 = 18
3 15 3 + 15 = 18
A - B = 18
A B
20 2 20 - 2 = 18
19 1 19 - 1 = 18
AB = 18
A B
1 18 1 * 18 = 18
2 9 2 * 9 = 18
3 6 3 * 6 = 18
A/B = 18
A B
18 1 18/1 = 18
36 2 36/2 = 18
