3 - Take The Easy Route
See if you can spot
easy way to do everyday math sums.
For example, suppose you need to find: 7 + 8 + 3.
Instead of starting at
left and adding as you go, you may notice that
7 and 3 make a nice round 10. Simply tag on
8 and you get 18 altogether.
The above technique - called "looking for 10s" - is a useful trick when adding numbers.
Try some for yourself:
a) 8 + 6 + 2 + 6 + 4
b) 9 + 3 + 7 + 5 + 1
c) 13 + 6 + 7 + 14
4 - Notice Patterns
Another thing to practice is seeing patterns in numbers. This makes them easier to remember and to work with.
For example, 23434 contains a simple pattern.
So does 9639.
And 51015 is a 'palindrome" - it's
same backwards.
5 - Make Them 'Real'
Numbers may contain memorable digits like dates.
For example, 217761.
If you look carefully, you'll notice it contains
year of
signing of
American Declaration of Independence.
A number could contain:
- birthday numbers of yourself, family, or friends
- figures from a telephone number or dial code
- numbers of a house you have lived in
Or some other kind of digit combination that you can relate to.
Once you can relate numbers to
'real world', you're fast on
way to becoming familiar with them.
And when you get to know them, you and numbers can become
best of friends for life!
