*** aNumber**- Subtract the receiver and aNumber, answer the result
**+ aNumber**- Sum the receiver and aNumber, answer the result
**- aNumber**- Subtract aNumber from the receiver, answer the result
**/ aNumber**- Divide the receiver by aNumber, answer the result (no loss of precision). Raise a ZeroDivide exception or return a valid (possibly infinite) continuation value if aNumber is zero.
**// aNumber**- Return the integer quotient of dividing the receiver by aNumber with truncation towards negative infinity. Raise a ZeroDivide exception if aNumber is zero
**\\ aNumber**- Return the remainder of dividing the receiver by aNumber with truncation towards negative infinity. Raise a ZeroDivide exception if aNumber is zero
**quo: aNumber**- Return the integer quotient of dividing the receiver by aNumber with truncation towards zero. Raise a ZeroDivide exception if aNumber is zero
**reciprocal**- Return the reciprocal of the receiver
**rem: aNumber**- Return the remainder of dividing the receiver by aNumber with truncation towards zero. Raise a ZeroDivide exception if aNumber is zero
