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:
