RED Calc Free and RED Calc Pro
Math On-the-Fly. When you are using RED Calc Free and RED Calc Pro, you don’t need an extra calculator or your smartphone for side calculations, such as floor area; just use math on-the-fly! This time-saving feature allows you to use simple math notation to perform calculations within most input boxes of our RED tools. The available mathematical operations include +, -, *, /, and “( )”; or addition, subtraction, multiplication, division, and parentheses.
RED Calc Free allows math on-the-fly in most input boxes similar to Figure 2, below. The calculated floor area, equaling 2,200 square feet, appears when you click outside of the Floor area input box. If you need to edit the calculation, click back in the Floor area input box and change whatever you wish.
Context-sensitive pop-up help and math on-the-fly are very helpful and time-saving features of both RED Calc Free and RED Calc Pro tools. Make sure you use them often.
