# Make up as many expressions with numbers (no variables) as you can from three numbers 5, 7 and 8. Every number should be used not more than once. Use only addition, subtraction and multiplication.

**Solution:**

Some of the expressions formed by 5, 7 and 8 are as follows:

(a) 5 × (8 - 7)

(b) 5 × (8 + 7)

(c) (5 + 8) × 7

(d) (8 - 5) × 7

(e) (7 + 5) × 8

(f) (7 - 5) × 8

Therefore, 5 × (8 - 7), 5 × (8 + 7), (5 + 8) × 7, (8 - 5) × 7, (7 + 5) × 8, and (7 - 5) × 8 are the some of the expressions formed by 5, 7 and 8.
