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.
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.
Use BIDMAS meaning order of operations are brackets, indices, division, multiplication, addition and subtraction
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.
To check a subtraction problem, you can add the result of the subtraction to the smaller number. If the sum equals the larger number, the subtraction is correct. Alternatively, you can use estimation by rounding the numbers to see if the difference falls within a reasonable range. Double-checking the numbers involved also helps ensure accuracy.
because you undo the operation in the equation= to undo subtraction you add
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.
it is the number you would use to solve the problem

You don't. You use the GCF to reduce the answer once the addition or subtraction is complete.

that we can use it
In addition to his response I vote yes. or I like addition better than subtraction.
because you undo the operation in the equation= to undo subtraction you add
They both include number and they use your head
Basic addition and subtraction mostly.
