Description

• The subtraction calculator finds the difference between two numbers by subtracting one number from another.

Facts about Subtraction

• Subtraction is an arithmetic operation that involves taking something away from a group of things.
  • For example, if you have 10 apples and take away 2, then you are left with 8 apples.
• Subtraction reduces the number of things in a group.
  • For example, if you have 2 baseballs and subtract 1, then you now have only 1 baseball left.
• Subtracting zero from a number does not change the value of the number.
  • For example, if you have 4 grapes and you take away zero, then you are still left with 4 grapes.
• Subtraction is part of the four basic arithmetic operations in mathematics.
• The arithmetic symbol for subtraction is the minus sign -.
• Many animal species have a natural ability to perform simple addition and subtraction.
• Subtraction is used in many areas of mathematics, including algebra, geometry, and calculus.
• Subtraction is an important foundational skill for many higher-level math concepts, such as fractions, decimals, and percentages.
• The concept of negative numbers is closely related to subtraction. Negative numbers are used to represent quantities that are less than zero, which can occur as a result of subtracting a larger number from a smaller one.
• Subtraction can also be used to compare two quantities, such as finding the difference between two prices or two temperatures.
• Subtraction is used in many real-world situations, such as calculating change at a store, determining the amount of time elapsed between two events, or figuring out the distance between two points.
• Subtraction can be thought of as the inverse operation of addition. For example, if 4 + 3 = 7, then 7 - 3 = 4.
