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 (see Inserting equations).
Consider the following when you write equations:
Write each symbol clearly and don’t overlap symbols.
Leave space between the characters, symbols, formulae 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 Maths Tools recognises log (N) as log10N.
SMART Notebook Maths Tools recognises logM as logm or logM (natural log).
SMART Notebook Maths Tools supports log2M and log10M only.
Write the natural logarithm (ln) as log.
Write log2 as log2. Write log10 as log10. SMART Notebook Maths Tools doesn’t support subscripts.
SMART Notebook Maths Tools can solve some multiple-lined equations if you select all the equations, press the equation’s menu arrow and then select Recognise Maths Ink.
