Combine like terms and write the expression in canonical form.
3a + 5 − a + 2 =
Answer like "2a + 7", "−3a − 5" or "5" (if the variable cancels out).
What does this generator do?
The generator builds an expression with 2–3 terms in "a" and 1–2 constants, in random order. Combine the like terms.
How to solve it
Terms with the same variable (e.g. "3a" and "−a") combine — the resulting coefficient on "a" is the sum of the coefficients. Plain constants combine separately. Write the result as "coefficient·a + constant".
