Basic Operations

Addition of numbers:
learn to group so that you get groups of 10, 100,...
13 + 28 = 13 + 27 + 1 = 41, 123 + 89 = 120 + 80 + 3 + 9 = 212
Subtraction:
learn to add a horizontal line of numbers and learn to look for patterns that make subtraction easier
121 - 23 = 121 - 21 - 2 = 100-2 = 98, 304 - 120 = 324 - 120 - 20 = 204 - 20 = 184
You will develop your own way of grouping - this is just a suggestion, do what you are comfortable with
Products:
practice multiplication, know your multiplication facts, know the rules when multiplying by 10, 100, 100
