Description

• The addition calculator finds the sum of two numbers by adding one number to another.

Facts

• Addition is an arithmetic operation that involves combining or adding things together.
  • For example, if you have 10 apples and add 2, then you now have 12 apples.
• Addition increases the number of things in a group.
  • For example, if you have 2 baseballs and add 1, then you now have 3 baseballs.
• Adding zero to a number does not change the value of the number.
  • For example, if you have 4 grapes and you add zero, then you are still left with 4 grapes.
• Addition is part of the four basic arithmetic operations in mathematics.
• The arithmetic symbol for addition is the plus sign +.
• The associative property of addition states that the grouping of the numbers being added does not affect the sum. For example, (2 + 3) + 4 is the same as 2 + (3 + 4).
• Addition can be performed using a variety of methods, including counting on, using a number line, or using regrouping or carrying.
• The result of an addition equation is called the sum.
• Addition was first used by ancient civilizations such as the Egyptians, Babylonians, and Chinese.
• Addition is commutative, meaning the order of the numbers does not affect the sum.
• Addition is associative, meaning a set of numbers can be grouped in any way, and the sum remains unchanged.
• Addition is the inverse operation to subtraction, i.e. it undoes what subtraction does.
• Addition is used in mathematics to simplify equations and solve problems.
• Addition is an important skill for young children to learn, as it is one of the building blocks of mathematical thinking and problem-solving.
• The ability to perform addition quickly and accurately is often viewed as a sign of intelligence and mathematical ability, and is an important skill for success in many fields.
