Rounding is when you make the number go up by 1 when it is 5 or more in a one digit number. When it is a two digit number, the number in the ones place has to be 5 or more to round up which means to make the number go up. When a number in the ones place is less than 5, you have to make the number goes down. For example, if you have the number 59, you would round up and it would be 60 or if you had the number 52, you would go down and the number would be 50. Rounding is also done after you solve an equation. For example, when you have an equation like 25+61, you would first have to solve the equation normally and then you round the answer. 25+61=86. 86 is rounded to 90 and that is your answer for an equation that is needed to be rounded. Estimating is when you have an equation and you round up or down before you solve the equation.
