Estimation is the process of making quick mental calculation of a value, quantity, or number.
We basically do estimation every day of our lives.
For example, we want to order several pizzas. We know that each pizza costs between $5 to $10. We order 3 pizza pies; Pie 1 = $6; Pie 2 = $8; Pie 3 = $9.
In getting an estimate, we either overestimate or underestimate. We know that whether a product of an estimate is overestimated or underestimated by the direction of the rounded up numbers.
We overestimate, when we round up the numbers
We underestimate, when we round down the numbers.
Overestimate: $10 x 3 pizza = $30 total cost
Underestimate: $5 x 3 pizza = $15 total cost
Actual cost: $6 + $8 + $9 = $23
In estimating expenses, it is better to overestimate. This gives us an allowance when incidental expenses incur.
In estimating income, it is better to underestimate. It gives us a more realistic value of the income.

Step-by-step explanation:
10x1 is 10. 10x10 is 100. but if u did 100x10 you would add the amount of zeros total. which would be 1000. so 400x10 is 4000
