If you can't do it in your head, try to find the answer on paper, if it doesn't look right then do it on a calculator. If it still doesn't look right the just put something random down. GOOD LUCK!!!

Depends on the operator precedence...
3+(45/5)-7+23 = 28
A computer or calculator would give this answer, as multiplication takes precedence over addition/subtraction.
But...
(3+45)/(5-7+23) = 48/21 = 2.29
