Identification by structure.
AskSia matches terms by their variable and exponent signatures.
Type or photograph the expression. AskSia identifies like terms by their variable and exponent structure, combines them by adding coefficients, and presents the simplified expression.
Like terms are terms in an algebraic expression that have the same variables with the same exponents. The coefficients can differ. For example, 3x and 5x are like terms (both x to the 1), as are 2x squared and minus 7x squared (both x to the 2). Terms with different variables or different exponents are not alike (3x and 3x squared are not like terms; 3x and 3y are not). To combine like terms, add their coefficients while keeping the variable part unchanged.
Every step transparent, every answer self-checked.
AskSia matches terms by their variable and exponent signatures.
Like terms combined by adding their coefficients.
Result organized from highest to lowest degree (descending order).
Expressions with multiple variables get terms matched by their full variable signature.
Snap handwritten or printed problems with your phone, paste from any online homework portal, or type with full LaTeX support.
Every answer gets a self-check pass. Sia catches sign errors and algebra mistakes before you submit your homework.
Type the expression, paste from your homework, snap a photo, or speak it. AskSia parses your input and identifies the structure.
Based on the problem structure, AskSia chooses the cleanest solution path and labels each step with the operation performed.
Final result appears with a substitution or composition check. Practice problems on the same concept are one tap away.
Every solve syncs across Web, iOS, and Android — start it at your desk, finish on your phone.
Split-panel interface with the worked solution on the left, the auto-generated diagram and AI tutor chat on the right.
Open the camera, frame the problem, and the worked solution plus diagram appear in seconds.
Combine all like terms into single coefficients.
Distribute first, then combine like terms.
Terms like 3xy and minus 2xy combine; xy and yx are the same.
After substituting values, combine numerical-like terms.
Make expressions easier to read and analyze.
Paste your candidate answer and the original problem. AskSia walks the work, flags any divergent step, and tells you the correct final value.
