A+63 b+52c equal if a=6, b=51 and c=1/4

I did both things cas you left a space in between 63 b
A + 63 + b + 52c        or        A + 63b + 52c
6 + 63 +51+ 52 * 1/4             6 + 63 * 51 + 52 * 1/4
6 + 63 + 51 + 13.5                 6 + 63 * 51 + 13.5
69 + 51 + 13.5                       69 * 51 +13.5
120 + 13.5                             3519 + 13.5
133.5 0r 133 1/2                    3532.5 0r 3532 1/2
