Front-end estimation is a particular way of rounding numbers to estimate sums and differences.
To use front- end estimation, add or subtract only the numbers in the greatest place value. Then add the decimals rounded to the nearest tenth.
Step-by-step explanation:
In front end estimation we are going to replace the original number with a number that is close by but only has one non zero digit. Examples: {20, 300, -50, 1,000, 80,000}. For example take the number 32, the choices to replace it with are 30 or 40 (they both have only one non-zero digit).
Since the exponent of the scientific notation is positive 4, move the decimal 4 places to the right
