a. 54 + 7 _ 3 - 20 / 4 = 70
b. 16 _ 8 - 9 _ 9 x 2 = 0
c. 4 _ 6 / 8 _ 32 - 12 = 23
_ being the blank, / being division
example, 21 / 3 x 7 - 6 + 3 = 47

I think you have missed brackets ( ) from these equations
a) could be 54 +(7x3)-(20/4)= 70

I believe your example is wrong - I get 46 - let me work on b and c and I'll get back to you.
b is 16/8 - 9/9x2 = 2-2 = 0
c is 4x6/8 +32 - 12 =23 because 24 / 8 is 3; 3 + 32 is 35; 35-12 = 23
a's answer from brum...is right except the parentheses are not needed because by order of operations you do the multiplying and dividing first anyway
