Remember for each question you solve you can only use the three numbers given once and the symbols given once too. ​

Answer 1

• 48 = (2 +4)×8
• 40 = (2 +8)×4
• 24 = (8 -2)×4
• 64 = 2×4×8

Explanation:

You want expressions that have values 48, 40, 24, 64 using the numbers 2, 4, 8 exactly once in each expression.

48

48 = (2 +4)×8

40

40 = 4×(2 +8)

24

24 = 4×(8 -2)

64

64 = 2×4×8
