The Basic Skills
Properties of Zero:
1. 0 added to any number is the number. 5 + 0 = 5
2. 0 subtracted from any number is the number. 5 - 0 = 5
3. The difference between any number and itself is 0. 5 - 5 = 0
4. When 0 is multiplied by 0, the product is 0. 0 x 0 = 0
5. When any other number is multiplied by 0 the product is 0. 5 x 0 = 0
Properties of One:
1. Any number multiplied by one is the number. 5 x 1 = 5
2. Any number , except 0, divided by itself equals 1. 5 ÷ 5 = 1
3. One raised to any power is 1. 1 5 = 1 x 1 x 1 x 1 x 1=1
Solving Word Problems
Word problems are math questions in sentence form. Finding the answer is
called solving the problem.
For example: Lucy Smith earns $1,500 each month. How much does she earn in
a year
1. Read and reread the problem.
2. What does the problem ask you to do
3. What facts are you given Sometimes you are given facts that you do not
need and sometimes you have to know facts that are not given.
4. Look for clues to help you decide what operation – addition, subtraction,
multiplication or division – you need to use.
