Multiplication and Division

Use any standard linear notation for multiplication and division.

$\blacktriangleright$ With the insertion point in the product (or quotient) choose Evaluate

82×37 =  3034 4pt

$\left(\vphantom{ 936}\right.$936$\left.\vphantom{ 936}\right)$$\left(\vphantom{ -14}\right.$ -14$\left.\vphantom{ -14}\right)$ =   -13104 4pt

${\dfrac{{2}}{{3}}}$  ${\dfrac{{8}}{{7}}}$ =  ${\dfrac{{16}}{{21}}}$ 4pt

82÷37 =  ${\dfrac{{82}}{{37}}}$ 4pt

36/14 =  ${\dfrac{{18}}{{7}}}$ 4pt

${\dfrac{{-\frac{2}{3}}}{{\frac{8}{7}}}}$ =   - ${\dfrac{{7}}{{12}}}$ 6pt

85$\left(\vphantom{ 13+5}\right.$13 + 5$\left.\vphantom{ 13+5}\right)$ -27$\left(\vphantom{ 16-3}\right.$16 - 3$\left.\vphantom{ 16-3}\right)$ = 1179

Important    Except that it be mathematically correct, there are no rules about the form for entering a mathematical expression.

For example, the expressions

$\displaystyle {\frac{{\frac{2}{3}}}{{\frac{8}{7}}}}$         $\displaystyle {\frac{{2}}{{3}}}$÷$\displaystyle {\frac{{8}}{{7}}}$         $\displaystyle {\frac{{2}}{{3}}}$/$\displaystyle {\frac{{8}}{{7}}}$        $\displaystyle \left(\vphantom{ 2/3}\right.$2/3$\displaystyle \left.\vphantom{ 2/3}\right)$/$\displaystyle \left(\vphantom{ 8/7}\right.$8/7$\displaystyle \left.\vphantom{ 8/7}\right)$

are equally acceptable ways of entering a quotient of fractions. Also,

$\displaystyle \left(\vphantom{ 936}\right.$936$\displaystyle \left.\vphantom{ 936}\right)$$\displaystyle \left(\vphantom{ 14}\right.$14$\displaystyle \left.\vphantom{ 14}\right)$     936⋅14     936×14    $\displaystyle \left(\vphantom{ 936}\right.$936$\displaystyle \left.\vphantom{ 936}\right)$ * 14     936$\displaystyle \left[\vphantom{ 14}\right.$14$\displaystyle \left.\vphantom{ 14}\right]$

and many other variations are acceptable. Scientific Notebook provides a completely natural way for you to enter and perform mathematical computations.

Exception    One of the few exceptions to the claim of ``no rules'' is the following. The ``vertical'' notation such as

24 +15
and
235 -47
and    2$\displaystyle \overline{{)364}}$

used when doing arithmetic by hand is not generally recognized in Scientific Notebook. Write sums and differences of numbers in ``linear'' notation, such as 24 + 15 and 235 - 47 and 364/2 or ${\frac{{364}}{{2}}}$ or ÷2.
