Estimating 26 plus 78 as 25 plus 75 is a form of rounding that simplifies the calculation while maintaining the overall magnitude of the numbers involved. By rounding down to 25 and 75, you are working with numbers that are easier to mentally add together quickly. This estimation technique is particularly useful when you need a rough answer or when exact precision is not necessary.
