Basic Calculations and Practices on Mental Math
Students need the best teacher, so you need examples, because
examples are the best teacher. All the examples here are fully
worked, and help you run your math better.
These are designed to help you do practices for your mental math,
calculation by heart. So these help improve your mental math.
Why mental math, though?
Your mental math will help you stay focused when you think, as
well as when you do math. The more mental math you do, the less
you get distracted. More likely to stay focused if doing math
mentally. In particular, it can help those people or seniors who are
concerned about memory loss.
And these are Basic Mental Math Step 1, Basic Mental Math Step 2,
Basic Mental Math Step 3, and so on. Up to 8 steps.
Each is a practice set, made of examples of simple calculations,
very simple. Even just reading them, your mental math improves.
When reading those examples, you are, kind of, forced to do
mental math.
With no pressure, though.
Reading and repeating those examples, you get to break a number
into other numbers and put them together some different ways.
Sounds hard, doesn’t it?
No worries. It begins with some easy ones, very easy, and
gradually, leads you to the ones bit more involved, bit by bit.
Actually, you’re doing calculations mentally in parts. And your
mental math grows.
As getting used to each step of practice, Step 1, Step 2, Step 3,
and so forth, up to Step 8, you keep growing your mental math, so
you can stay focused better when you are thinking, as well as
when you are doing math.
So this is for you if you want to get used to some basic math skill
so that you can get and do some essential math right and fast
enough.
As you get used to it, your mental math keeps growing, and gets
easier, smoothly faster.
And these are also, particularly for you if you have a difficulty
learning math as math anxiety or phobia. So anyway somehow if
math is daunting you, these are right for you.
Thus, if you hate math or struggle with it, but you want to learn it
right so that you can do some essential math right, smooth, and
fast enough, you are looking at the right books right now.
And handy and wieldy.
These books are small enough to carry and have fonts large
enough to read, so they can be in your pocket, can always be with
you, and can be an easy read whenever you have time for it.
