Generated value: `integer`

→ Used by:

This variable doesn't seem to be used anywhere.

Advice

First work through the expression from left to right, evaluating any multiplications and divisions as you come to them. You should be left with an expression involving only pluses and minuses. Evaluate this expression, again working from left to right. Thus:

$\var{a}+\var{b} \times \var{c}=\var{a}+\var{b*c}=\var{a+b*c}$

$\var{a} \times \var{b}+\var{c}=\var{a*b}+\var{c}=\var{a*b+c}$

$\var{h}-\var{a2*b2} \div \var{b2}=\var{h}-\var{a2}=\var{h-a2}$

$\var{a} \times \var{b}+\var{c*d} \div \var{d} - \var{f} \times \var{g}=\var{a*b}+\var{c}-\var{f*g}=\var{a*b + c-f*g}$

$\var{a1*b1} \div \var{b1}-\var{c1} \times \var{d1} - \var{e1*f1} \div \var{f1} \times \var{g1}=\var{a1}-\var{c1*d1}-\var{e1*g1}=\var{a1-c1*d1-e1*g1}$
