Arithmetic operation instruction

An arithmetic operation instruction instructs the addition, subtraction, multiplication or division for two BIN data, or operation of
increment or decrement.
BIN arithmetic operation (binary)
• If the operation result of an addition instruction exceeds 2147483647, the value is negative.
• If the operation result of a subtraction instruction is smaller than -2147483648, the value is positive.
• Operations of positive values and negative values are as follows.
5 + 8  13
5 - 8  -3
5  3  15
-5  3  -15
-5  (-3)  15
-5  3  -1 remainder -2
5  (-3)  -1 remainder 2
-5  (-3)  1 remainder -2
