What is Fast Math Calculation Tricks about?

This document provides several math calculation tricks for quickly solving addition problems mentally or with minimal writing. It includes tricks for: 1. Adding numbers by converting them to the nearest hundred or ten (e.g. 415 + 94 as 515 - 6). 2. Adding similar digits by taking the common digit and replacing others with 1 (e.g. 5 + 55 + 555 as 5(1 + 11 + 111) = 5 x 123 = 615). 3. Adding numbers with decimals using the same approach as above (e.g. .5 + .55 + .555 as 5(0.1 + 0.11 + 0.111) = 5 x 0.321
