The word subtraction derives from the Latin "restis" means "agree" the subtraction also known as subtraction where it is ordered as soon as a number is greater, called "minuend" which is the quantity that is subtracted from another quantity in order to obtain the difference for example 5 - 3 = 2 in this case the minuend is 5 and the subtrahend is 3, but the "subtrahend" is the quantity to be subtracted from another, for example 10 - 8 the subtrahend would be 8. Subtraction is a procedure of the part of mathematics that is symbolized by the sign(-), this symbol represents the execution of the object removal from a collection.
If instead of being the ones that subtract quantity from a figure, they had to change, that is, the appropriate quantities must be successively subtracted from the various subtrahend mandates from those of the minuend. If one of the quantity of the minuend corresponding to the number, ten, hundred, among others.
If the amount is less than the subtrahend, that number can be borrowed from the number to its left.
The subtraction is the opposite of the addition that can be said that a + b = c, like c - b = a 8 + 3 = 11, 11 - 8 = 3, it is very important to take into account that the frame provides natural numbers and it is only possible to subtract two numbers as long as the main minuend is greater than the second subtrahend. If this is not true, the inequality of the result to be obtained must be negative, we can say, 5 - 4 = 1, 4 - 5 = -1.
