INSTRUCTIONS

The following picture was made from Add With Like Denominators:

The parts of an addition example are the first addend, the second addend, and the sum.

When the program starts, you will be asked to identify the first addend and then the second addend. The program will not continue unless each addend is correctly identified. You will then be asked to add each addend for the sum.

In many examples, the sum may be found by visually combining the two addends. You can see from the picture that the first addend is 2 2/6 circles and the second addend is 1 2/6 circles. The sum will combine all the whole numbers and then the fractional parts in the two addend circles for a sum of 3 4/6 circles. Notice how we added the whole numbers 2 and 1 first and then red fraction 2/6 and the blue fraction 2/6.

To calculate the sum first add the whole numbers 2 and 1 to obtain 3 for a whole number. Then add the numerators of the fractions 2/6 and 2/6 to obtain 4/6. The example can be written out as shown:

You may prefer to work vertically:

You may prefer to write each addend in fraction form first as in this example:

You may enter the sum in fraction form or mixed number form. In the above example 22/6 or 3 4/6 are both acceptable.
