You can use addition to check your answer to a subtraction problem because subtraction is the inverse operation of addition. If you subtract a number from another and then add that same number back to your result, you should arrive at the original number. This relationship confirms the accuracy of your subtraction result, ensuring that the calculations are correct. If the sum does not match the original number, then there was likely an error in the subtraction process.
What else can I help you with?
When addition subtraction and multiplication are use in a problem in that order which get done first?
In mathematical operations, addition, subtraction, and multiplication are governed by the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). When addition, subtraction, and multiplication are used in a problem, multiplication is performed first, followed by addition and subtraction, which are executed from left to right. Thus, in a sequence where these operations appear together, multiplication takes priority over addition and subtraction.
How do you decide what operation you use to solve a problem?
Use BIDMAS meaning order of operations are brackets, indices, division, multiplication, addition and subtraction
How do you check a multiple addition problem?
To check a multiple addition problem, you can use the following methods: First, add the numbers again to verify your original sum. Second, you can group the numbers in pairs or tens to simplify the addition process. Lastly, using the inverse operation of subtraction, subtract the individual numbers from the total to see if you return to zero. This helps ensure accuracy in your calculations.
Why would you use addition to solve a subtraction equation?
because you undo the operation in the equation= to undo subtraction you add
What is the answer to a subtraction problem that teaches use?
1-infinity
Why can you use addition to check your subtraction?
Addition is the opposite of subtraction. For example, 24 - 9 = 15. If you want to check your answer, add 9 + 15. It equals 24, so your answer is correct.
What does the variable represent in an addition or subtraction expression?
it is the number you would use to solve the problem

How do you use greatest common factor with addition and subtraction of fractions?
You don't. You use the GCF to reduce the answer once the addition or subtraction is complete.
How do you decide what operation you use to solve a problem?
Use BIDMAS meaning order of operations are brackets, indices, division, multiplication, addition and subtraction
What is the abacus use for?
