| A neat trick when trying to find 10% of a price....simply move the decimal ONE Place to the left ($438.00 ~ 10% =$43.80) | ||
| When ROUNDING...underline the first two numbers on the right side of the decimal...look at the THIRD number to see if it is a "magic number" (5, 6, 7, 8, or 9), if it is...dump a penny on the guy next door and it goes UP one penny!....if it is NOT a magic number....TRASH IT! | ||
| Power of "10" Add numbers that equal 10 ~ I say 6, YOU say 4 I say 9, you say 1 THEN you must always carry one to the guy on the left....(that number goes up by one). Example: you spend .48 at the store and pay with a dollar....I say 8 YOU say 2 The 4 goes up to a 5 I say 5 YOU say 5 The change you have coming back is .52 The only exceptions are when you get to WHOLE numbers ending in a zero such as 40....then you count up to 100! | ||
