It is evaluating the expression.
Algebra.
Always.
Set all numbers and variables equal to zero. (2x3)-(3x2)-(20x)-21=0 Next, follow the order of p.e.m.d.a.s. 6-6-20x-21=0 -20x-21=0 Separate the numbers and variables -20x=21 x= -21/20
Follow the rule about the order or operations!
No say you had 3to the 2nd power + 1 to the 2nd power. u would follow order of operations and multiply first. then u would add.
Substitution

It means that the calculator can follow the order of operations and do the order of operations for you but, you need to know how to do them on your own too.

In standard from the number precedes variables, and variables follow in alphabetic order. So it would be 6xy.
