Related facts are mathematical terms that consist by three numbers. They are typically taught as part of the curriculum for early math, along with fact families and multiplication, subtraction, addition and division knowledge. Read more Related Facts Math here!
Similar facts can be utilized to reinforce or teach students’ understanding of the interactions between the operations of subtraction and addition and multiplication and division.
Subtraction and Addition
Subtraction and addition are both inverse operations. If you add a number and subtract the exact number and subtract the same number, they cancel each other out, and there is no impact on the equation.
Example
Here are the additional subtraction and addition facts using the numbers 2 and 3:
2 + 3 = 5 3 + 2 = 5
5 – 3 = 2 5 – 2 = 3
Similar facts can be written to solve any addition or subtraction issue. If we have an example, we could create three more facts with identical three figures as well as subtraction or addition. Each of the expression sets (ex. 2 + 3 = 5 , 3+2 = 5) is called the fact family.
Division and multiplication
Division and multiplication, as well as subtraction and addition are both inverse operations. Both “undo” each other. By multiplying by a certain number, and then dividing that number will not alter the expression.
Example
Below are the relevant facts about division and multiplication with two and four as factors:
2 x 4 = 8. 4 x 2 = 8.
8 / 4 = 2 8 / 2 = 4
Like subtraction and addition each set of three numbers from the division and multiplication facts above forms a fact familythat could be utilized to compose an entire set of four related facts.
Recalling similar facts, especially in relation to division and multiplication will help to reduce the number of essential facts a child must remember. If a student can solve the multiplication problem that involves 2 numbers, they will also understand the connection between those two numbers and division.
