Entering Math Expressions

Math in a Mathcad worksheet appears in familiar math notation - division with a fraction bar, exponents in a raised position, and built-up fractions just as you would see in a book. Entering math expressions is very straightforward.

To enter mathematical expressions, you simply need to position the math editing lines in your worksheet and begin typing numbers or operators such as "+" or "−."

Entering mathematics:

When typing letters or numbers, you see them appear surrounded by math editing lines to show you which characters are selected.

You can insert operators by clicking on the appropriate button in the operator toolbars or by pressing the keystroke.

Mathcad's equation editor is designed to work within the structure of a mathematical expression so that expressions are not so much typed as they are built. Mathcad assembles the parts that make up an expression using the rules of precedence plus some additional rules to simplify entering denominators, exponents, and expressions in radicals.

Once your math expression is entered in your worksheet, you can evaluate it, following the rules for evaluation order.
