Two Boys And A Dad Productions How To Use The Compensation Strategy An explanation of how to use the strategy of compensation to do addition, subtraction, multiplication, or division. how to use compensation to do mental mat. Multiplicative compensation method. this compensation strategy makes complex numbers easier to multiply. let’s look at these two compensation strategy examples to understand this better. example 1: $76 \times 5$ let’s multiply 76 by 10 and compensate by dividing the answer by 2. $76 \times 5 = 76 \times \frac{10}{2} = \frac{760}{2} = 380$.

The Compensation Strategy For Subtraction Youtube The pemdas rule is a popular memory tool for recalling the math order of operations. the rule stands for p: parenthesis, e: exponents, m: multiplying, d: dividing, a: adding, s=subtracting. in general, operations are performed from left to right, but there are very important key sub rules, namely (1) perform multiplying dividing from left to. Start with: 7 (6 × 52 3) parentheses first and then exponents: 7 (6 × 25 3) then multiply: 7 ( 150 3) then add: 7 ( 153) parentheses completed: 7 153. last operation is an add: 160. learn how to calculate things in the correct order. calculate them in the wrong order, and you can get a wrong answer!. The compensation strategy for multiplication involves multiplying by a multiple of 10 and then subtracting lots of a number afterwards. for example, to multiply a number by 9, multiply it by 10 and then subtract 1 lot of that number. to work out 14 × 9, work out 14 × 10 and then subtract 1 lot of 14 14 × 10 = 140. Without strategy, adding, subtracting, multiplying, and dividing can be tedious. learn to use place value strategies like compensation and expanded notation to solve multi digit arithmetic problems.
