The number we get is the tens digit in the product. If it is greater than 5 (between 6 and 10), we subtract 2. If it is less than or equal to 5 (between 1 and 5), we subtract 1. To calculate an exercise involving multiplication by 8, we will look at the number that appears in the exercise. How do you easily calculate multiples of 8? In multiples of 8 we count eights, that is, groups of 8. Multiples of 6 are even numbers, meaning their unity digit belongs to the group: 0, 2, 4, 6, 8. When there is an exercise that involves multiplying by 6, raise your fingers according to the number that appears in the exercise and say the multiples in order, a multiple for each finger.įor example, to calculate 5×6, lift 5 fingers and count as follows: 6 for the first finger, 12 for the second finger, 18 for the third finger, 24 for the fourth finger, and 30 for the fifth finger. Start from the number 6 and add 6 each time. Method 2: It is possible to remember multiples of 6 in order. Method 1: When you want to calculate an exercise with a number that is multiple of 6, you can calculate the same exercise, but with 5 instead of 6 and add the number that appears in the exercise. How do you easily calculate multiples of 6? In multiples of 6 we count sixes, that is, groups of 6.
