SMART Notebook 10 for Windows Operating Systems
You can write equations on the page using pen tray pens (on interactive whiteboards) or a tethered pen and pen tool buttons (on interactive pen displays).
NOTE: You can also insert equations using the equation editor.
Press Pen , and then select an available line type.
NOTE: Don't select a creative pen.
Write the equation on the interactive screen using the tips below.
Select the equation.
Press the equation's menu arrow, and then select Recognize Math Ink.
The equation appears surrounded by a blue border. A green circle 
and a red circle 
appear below the equation.
If the equation appears correctly, press the green circle .
SMART Notebook Math Tools recognizes many characters, including numbers, operators, Roman letters, Greek letters and other mathematical symbols. SMART Notebook Math Tools also recognizes many mathematical functions.
NOTE: If you write a mathematical expression, you can solve the expression. You can also generate a graph based on this equation.
If your equation appears incorrectly, press the red circle , erase the equation and write it again. Don't attempt to write over your original equation.
Consider the following when you write equations:
Write each symbol clearly and don't overlap symbols.
Leave space between the characters, symbols, formulas and equations that you write.
Draw a multiplication symbol as a six-pointed asterisk, for example, 
.
If your equation involves multiple lines, such as fractions, leave space between these lines. However, don't separate a single line equation over multiple lines.
Align superscripts, such as exponents, to the right of and above the adjacent character or symbol. Don't allow a character and a superscript to overlap.
Write problems sequentially from left to right and from top to bottom.
Tap to make a decimal point. Don't draw a tiny ball or scribble a mark.
Don't use j as a variable unless you're writing a trigonometric expression or a complex expression. Don't use i or o as variables unless you're writing a trigonometric expression.
Don't use e as a variable unless you're writing an exponential expression.
Enclose exponents in parentheses.
Consider the following when you write trigonometric equations:
Enclose variables in parentheses, for example, sin (x).
Separate multiple trigonometric expressions using a multiplication sign, for example, sin(A)*cos(A).
Consider the following when you write exponents, logarithms and geometric series:
SMART Notebook Math Tools recognizes log (N) as log10N.
SMART Notebook Math Tools recognizes logM as logm or logM (natural log).
SMART Notebook Math Tools supports log2M and log10M only.
Write the natural logarithm (ln) as log.
Write log2 as log2. Write log10 as log10. SMART Notebook Math Tools doesn't support subscripts.
SMART Notebook Math Tools can solve some multiple lined equations if you select all the equations, press the equation's menu arrow, and then select Recognize Math Ink.
