Final answer:
Estimation is useful for making quick and approximate calculations in mathematics and real-world problems. It helps to get an idea of the answer without performing lengthy calculations and is valuable for checking accuracy.
Step-by-step explanation:
Estimation in Mathematics
Estimation is useful when finding actual products and solving real-world problems because it allows us to make quick and approximate calculations that are close to the actual values. It helps us get an idea of what the answer might be without having to perform tedious and time-consuming calculations.
For example, if you are at a grocery store and want to estimate the total cost of your items before reaching the cash register, you can round the prices to the nearest dollar or make a quick mental calculation based on the prices you see.
Estimation is also useful when solving problems that involve large numbers or measurements. It helps us determine if our answer is reasonable and allows us to check the accuracy of our calculations.
