math worksheet named Calculating Codes
we are to fill in the correct signs (+ - X etc..) looks like we can't rearragne or create an order of operations other than the order of the signs.

the example is
1 2-3+4 5 = 54

1 2 3 4 5 = 60
only need two signs + and +

1 2 3 4 5 = 230
only need two signs + and x

1 2 3 4 5 = 11
only need three signs + divided by and +

1 2 3 4 5 = 51
only need three signs x + x
