YOUR ANSWER


  • Graphical form: -2%2An-%289-10%2An%29 simplifies to 8%2An-9
  • Text form: -2*n-(9-10*n) simplifies to 8*n-9
  • Cartoon (animation) form: simplify_cartoon%28+-2%2An-%289-10%2An%29+%29
    For tutors: simplify_cartoon( -2*n-(9-10*n) )

DETAILED EXPLANATION

Look at -2%2An-highlight_red%28+%289-10%2An%29+%29.
Remove unneeded parentheses around terms highlight_red%28+-9+%29,highlight_red%28+10%2An+%29
It becomes -2%2An-highlight_green%28+9+%29%2Bhighlight_green%28+10%2An+%29.
Look at -2%2An-highlight_red%28+9+%29%2B10%2An.
Moved -9 to the right of expression
It becomes -2%2An%2B10%2An-highlight_green%28+9+%29.
Look at -highlight_red%28+2%2An+%29%2Bhighlight_red%28+10%2An+%29-9.
Eliminated similar terms highlight_red%28+-2%2An+%29,highlight_red%28+10%2An+%29 replacing them with highlight_green%28+%28-2%2B10%29%2An+%29
It becomes highlight_green%28+%28-2%2B10%29%2An+%29-9.
Look at %28-highlight_red%28+2+%29%2Bhighlight_red%28+10+%29%29%2An-9.
Added fractions or integers together
It becomes %28highlight_green%28+8+%29%29%2An-9.
Look at highlight_red%28+%28highlight_red%28+8+%29%29%2An+%29-9.
Remove unneeded parentheses around factor highlight_red%28+8+%29
It becomes highlight_green%28+8+%29%2An-9.
Result: 8%2An-9

Universal Simplifier and Solver

Welcome to Graphical Universal Mathematical Expression Simplifier and Algebra Solver (GUMESS).
It solves most middle school algebra equations and simplifies expressions, and it SHOWS ALL WORK. It is free to use.

Enter expression to be simplified, or equation to be solved.
I will figure out if what you typed is an equation.

Enter Expression ==>     
Examples: x^2-2x=-1, 3x-x-x+a-a=5, (x^2-1)/(x+1), 2x-(x+x)


Single letter variables only, no functions, xy means x*y, x(x-1) means x*(x-1), sin(x) means s*i*n*(x)


You must use the "*" (star) symbol for all multiplications! x(x+1) is WRONG! It means a function x of x-1. x*(x-1) is right. Use the ^ (caret) for exponentiation. x^2 means x squared. x/2y means x%2F2y
Resources: Simplifier Portal, help with entering simplifier formulas (a must read).
