# Using only addition, subtraction and multiplication

I have the numbers 6, 30, 8, 8, 3, 7, 1, 2, and 5. Using only addition, subtraction, and multiplication, can you use those numbers to make 60, 54, and 52?

• Do I have to use all numbers provided? – user175968 Oct 14 '14 at 11:25
• And can one only use each number once? – AmagicalFishy Oct 14 '14 at 11:25
• Can you clarify this question please. Are you saying write three equations using the above numbers using addition, subtraction and multiplication only to give 60, 54 and 52 using each number no more than once across all three equations or using each number exactly once? – Warren Hill Oct 14 '14 at 11:40

$$6+30+8+8+3+7+1+2\color{red}{-}5=60.$$ $$6+30+8+8\color{red}{-}3+7+1+2\color{red}{-}5=54.$$ $$6+30+8+8\color{red}{-}3+7\color{red}{-}1+2\color{red}{-}5=52.$$
P.S. $$30\times 2=60.$$ $$6\times (8+1)=54.$$ $$(8+5)\times (7-3)=52.$$
