Multiplication and division

Usage

Multiplication in Mathsys is straightforward with the * operator:

* 13

* 7

Division is also available with the / operator:

/ 3

/ 9

You can combine them both in an expression:

* 3 / 5

* 7 / 11

/ 7 * 4

and operator precedence is respected with summation and subtraction:

1 + 1 / 5

Implicit multiplication

Multiplication is also available implicitly, without needing to write the operator each time:

A space is not required between variables and numbers.

Fraction carryover

Fraction carryover is the property that allows you to maintain the position on a fraction when relying on implicit multiplication. It means that whenever * is used, the position is reset to numerator, but if implicif multiplication is used, the position is inherited from the previous element:

# this is three times y
3y

# this is one over (two x)
1 / 2x

# this is six over (seven times eight)
6 / 7 8

# this is one half times four
1 / 2*4
