When we add two numbers, it is easy to think that each number represents a number of pennies. 

\n

For example, if the expression is 8+4 you may think that you have 8 pennies and add 4. If you count the total amount of pennies, you get 12.

Then 8+4 must be 12.

When you subtract a number from another, you may think of it as taking away a number of pennies from another number of pennies.

\n

If the expression is 8-4, then you take 4 pennies from your original amount of 8 pennies. If you count your remaining pennies, you get 4.

\n

Therefore 8-4=4.

But, what if we subtract a number that is larger then the first number? Well, think of it as you owe money. For example 4-8 = -4. In this case, you owe 4 pennies.

Again think of pennies, whether it is adding or subtracting. If the expression is 8+4-6, then you start out with 8 pennies and add 4 pennies which is a total of 12 pennies. Then you subtract 6 pennies from 12 and end up with 6 pennies left.
