How do you solve equations that contain addition or subtraction

Mathematics

ollegr [7]3 years ago

To solve an addition problem, you simply add one number to the other. For example, If I want to add 4 to 5, I would write the equation 4 + 5 = 9. To solve a subtraction problem, you simply take a number away from another. For example, If I want to take 5 away from 9, I would write the equation 9 - 5 = 4. Hope I helped! :)
