The answer to a subtraction problem is called the difference. The value being subtracted is called the subtrahend, and the value from which the subtrahend is being subtracted is called the minuend.
Know MoreFor example, in the subtraction problem 5 - 3 = 2, 5 is the minuend, 3 is the subtrahend and 2 is the difference. These terms hold for subtraction of any types of numbers, including decimals, fractions, negative numbers, mixed numbers and imaginary numbers. Similarly, the answer to an addition problem is called the sum, while the answer to a multiplication problem is called the product. The answer to a division problem is called the quotient.

Full Answer >Binary subtraction is a mathematical operation where one binary number is subtracted from another. Standard techniques adopted for decimal numbers are used to do the deduction. That is, the subtraction of each bit pair takes place from right to left.
Full Answer >When subtracting two numbers, regrouping means starting at the ones column and borrowing a value from the next column as one moves to the left until the subtraction is completed. "Regrouping" and "borrowing" are words that mean the same thing when subtracting.
Full Answer >Technically, the square root of a negative number cannot be taken, but if imaginary numbers are allowed, the answer would be 2i. It can be tempting for those people just learning how to deal with square roots to assume the square root of -4 would be -2, but this does not work because when -2 is multiplied by -2, the result is 4 rather than -4.
