This post is for all those people who consider themselves bad at maths.
This post reblogged from BabaMail shows seven different ways to think about math concepts using fingers, lines and illustrations - a different way to learn some vocabulary and and practise your reading comprehension in English
Math Tips You Wish they Taught in School
It’s been a while since we attended school and age hasn’t been kind to our memory either. As time passes, most of us lose most of our mathematical abilities leading us to rely more and more on calculators. If you want to improve your math skills and even be able to help your kids, learn how to use these quick and easy methods.
1. Calculate multiplications of 6,7,8,9 by using your fingers
Did you ever memorize the classic multiplication table? While calculating multiplications of 1-5 are usually easy, when we go to 6 and higher, many of us start to stutter. This easy method is not taught in most schools, but it’s very quick and intuitive:
2. Quickly calculate multiplications of 9
To calculate the multiplications of nine, you just need to remember that the tens increase and the units decrease, and the sum of the total always equals nine.
3. Calculating multiplications of eleven with 2-digit numerals
4. Quickly calculate fractions
Even though fractions are not something most of us deal with on a daily basis, this method is very useful, especially for school-age children.
5. Multiplying double-digit numbers
Multiplication can become harder when the numbers get bigger, but it doesn’t have to be. This method will help you get over this, and you’ll find that the larger the number – the easier it gets:
6. Multiplying double and triple-digit numbers
Another method to multiply double-digit numbers is the “line method”, which also works on multiplying triple-digit numbers. It is vital that you remember to maintain a left-to-right writing direction, even when drawing the lines:
To do the same for a triple-digit number, follow the same method, but notice that now you will have 4 sections instead of 3.
