What’s on the The Product Rule poster
The rule, 4 worked examples, and the mistake everyone makes.
- When multiplying powers with the same base, keep the base and add the exponents.
- aᵐ × aⁿ = aᵐ⁺ⁿ
- x³ × x⁴ = x⁷
- 2⁵ × 2³ = 2⁸ = 256
- 3x² × 4x⁵ = 12x⁷
- x × x⁶ = x⁷
- Common mistake: x³ × x⁴ = x¹² → x³ × x⁴ = x⁷
This only works when the bases match. x³ × y⁴ cannot be simplified at all.

- Who is the The Product Rule poster for?
- The Product Rule is filed under 8th Grade (ages 13–14), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting math, and to the parent or teacher answering the question at the kitchen table.
- When should you use the The Product Rule poster?
- Write it out longhand once. The rule stops feeling arbitrary immediately. A wall chart earns its place by being glanceable from where the work is happening, so The Product Rule belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with The Product Rule?
- The Power of a Power Rule, The Quotient Rule and Scientific Notation sit alongside The Product Rule in the 8th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.The Power of a Power RuleThe Quotient RuleScientific Notation
- Is the The Product Rule poster free to download and print?
- Yes. The Product Rule downloads as a free PDF with no account, no email and no watermark, like everything else in the 8th Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the The Product Rule poster print at?
- The Product Rule is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of The Product Rule loses nothing.Printing guide
