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
because you undo the operation in the equation= to undo subtraction you add
1-infinity
Order of Operations is like when you have a problem i always use PEMDAS it means parenthesis, expoents, mulitipication, divide, addition, Subtraction follow it.
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.

addition subtraction multiplication and division
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.
