**CHAPTER 5**

However, often, all you'll want is a rough estimate. Let’s say you are receiving quotes from different lenders to refinance your home. Everything really the need at this stage of information gathering is a rough estimate of what your monthly payments will be. Or say you are paying a restaurant bill with a group of friends and you do not want to include the account of each person to the penny. The

**MATHS TRICKS**guesstimation methods.

**MATHS TRICKS**GUESSTIMATION chapter will make these two tasks and much more equal to them, easier. Addition, subtraction, division, and multiplication lend themselves to

**MATHS TRICKS**guesstimation. As usual, he will do his calculations from left to right according to with the help of

**MATHS TRICKS**.

**MATHS TRICKS**formulas also provide you Guesstimation. Guesstimation is also a good technique to make your life easier when the numbers of Problems are too long to remember the trick is to round the original numbers up or down:

**MATHS TRICKS**case, you go only for 15,000, which is terribly close when it comes to numbers up to the third digit of the largest number (here the hundred thousand digits), your estimate will always be within 1% of the precise answer. If you can calculate exactly these smaller problems, you can Guesstimate the answer to any addition problem.

**MATHS TRICKS**subtraction problems are the same: you round to the nearest thousand or hundred digits, preferably the latter:

**MOD SUMS (CASTING OUT 9'S)**

**Mod sums**" (because it is based on the elegant mathematics of modular arithmetic).With the method of sums mod, you add the digits of each number until you stay with a single digit. For example, to calculate the mod sum of 4328, add 4 + 3 + 2 + 8 =17. Then add the digits of 17 to get 1 + 7 = 8. Therefore, the sum of the mod of 4328 is 8. For the in the following problem, the mod sums of each number are calculated as follows:
