Newline Engage Cloud Math Editor Detailed Help

We now support teaching mathematical equations directly in Newline Engage Cloud, our free, interactive, online whiteboard designed for teaching and learning.

Step 1: Select the “Text” tools from the left side menu. Then, select “Math Editor.”

Step 2: Click on the board and start typing your math equation. For details on how to build your complex equations, please refer to the information below.

Here are a few examples of some popular math equations:

Quadratic: #

For the equation shown below, type the following in your math editor box:

X = -b \pm \sqrt b^2 – 4ac (to add a denominator, select till -b using shift left) / 2a

Note: To bring the cursor back to normal level, from subscript or superscript, use arrows (up, down, left, right) or use the space bar. At any time, use arrow keys and space bar to move around the equation.

Use ^ for superscript in the example below.

Polynomials: #

For the equation shown below, type in the following in your math equation box.

5xy^2 – 3x + 5y^3 – 3

Fractions: #

For the equation below, type the following in your math equation box.

5x/2 = x + 5 (to add denominator select up to x using shift left) / 2

For the equation below, type the following into your math equation box.

6(2x+1 (to add denominator select up to 2x using shift left) /3 (now using space move the cursor outside of the ‘)’ = 6(x+4 (to add denominator select up to x using shift left) / 2

Summation: #

For the equation shown below, type the following in your math equation box.

\sum_ {j=o} (now move cursor up over the summation symbol) 3 (again move the cursor using up down arrow and space next to the summation symbol) j^2

Note: use “underscore” ‘_’ for subscript in the example below.

Integral: #

For the equation shown below, type the following in your math equation box.

y(t) = \int_0 (now use up arrow key to move the cursor to the top of integral) t (now use right arrow key to bring the cursor down to normal level) 2s – y(s) (to add denominator select up to 2s using shift left arrow) / 1 – y(s) (again use up arrow or right arrow keys to bring the cursor back to normal level) ds
