Calculations are performed in mathematical order - multiplication and division are performed before addition and subtraction.
The following equation solves to 1 (3×2 = 6, 7−6 = 1).
</p>
<example>
<p>
7−3×2
</p>
</example>
<p>
To change the order of calculation use parenthesis.
The following equation solves to 8 (7−3 = 4, 4×2 = 8).
</p>
<example>
<p>
(7−3)×2
</p>
