Program that will accepts 2 numbers and will display the sum,difference,product and quotient by the use of flow chart?

You can do this pretty easily in a spreadsheet program such as excel, open office or numbers on a mac. Simply use two cells for the numbers you would like as an input and then input formulas for the sum, difference, product and quotient in 4 other cells. Examples:

(This assumes you use A1 and B1 to hold your input numbers)
For sum you would input the formula: =A1+B1
For difference: =A1-B1
For product: =A1*B1
For quotient: =A1/B1

To get this into a flowchart simply go into "Insert > Chart" and select the chart you want to use with the correct options.

I hope this helps, if it does, please give a thumbs up!
