Money | Maths

Money is used for paying things such as food, home loans, etc. 

NZ money has 10c, 20c, 50c, $1, and $2 are coins and $5, $10, $20, $50, and $100 are notes. 

Example:

If someone had $10 and bought $1.50c chocolate bar and a $1.70c ice cream, how much money is left? We can solve this equation by using place value. First add 50c + 70c = $1.20c. Another way to solve this is: divide 70c into 20c and 50c. Next add 50c + 50c = $1. Then add $1 + 20c = $1.20c.  Next add $1 + $1 = $2. Then add $2 + $1 = $3. Finally add $3 + 20c = $3.20c.

It is important to know the use of money.
