Estimating

Estimating is when you round as many numbers as you have and then you ether add, subtract, divide or multiple the numbers. That number will be close to what your original number.
Example:

   4230 >4000
+3476 >3000
——— ———
              7000

 8578 >9000
- 4234 >4000
——— ———
              5000
