When you multiply two numbers, this is the same as adding the number to itself as many times as the value of the other number is. Multiplication is the third basic math operation. Subtraction can also be used to perform operations with negative numbers, fractions, decimal numbers, functions, etc. How many apples does she have? She has 3 apples (5 apples that she had – 2 apples that she gave to Paul = 3 apples that are left to her).Īs you can see, subtraction is determined by the “minus (-) symbol”. Subtraction is used when you want to know how many objects are left in the group after you take away a certain amount of objects from that group.įor example, Maggie has 5 apples. Subtraction is the arithmetic operation that is the opposite of addition. There are several arithmetic properties that are typical for addition: As you can see, the addition is signified by the “plus sign (+)”.Īddition can also be used to perform operations with negative numbers, fractions, decimal numbers, functions, etc. By adding them together, we see that both of them combined have 5 apples (2 Jimmy’s apples + 3 Laura’s apples = 5 apples in total). Keep in mind, even though the operations and the examples shown here are pretty simple, they provide the basis for even the most complex operations used in mathematics.Īddition is a mathematical operation that explains the total amount of objects when they are put together in a collection.įor example, let’s say that Jimmy has 2 apples and Laura has 3 apples, and that we want to find out how many apples they have together. In this and other related lessons, we will briefly explain basic math operations. Arithmetic is the oldest and most elementary branch of mathematics. These operations are commonly called arithmetic operations. Basic math operations include four basic operations:
