What’s on the Zero and Negative Exponents poster
The rule, 4 worked examples, and the mistake everyone makes.
- Any non-zero base to the power zero is 1. A negative exponent means the reciprocal —…
- a⁰ = 1 · a⁻ⁿ = 1/aⁿ
- 5⁰ = 1
- 2⁻³ = 1/8
- 1/x⁻² = x²
- (2/3)⁻¹ = 3/2
- Common mistake: 2⁻³ = −8 → 2⁻³ = 1/8
0⁰ is undefined. Every other base to the power zero is exactly 1.

- Who is the Zero and Negative Exponents poster for?
- Zero and Negative Exponents 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 Zero and Negative Exponents poster?
- A negative exponent is a location, not a sign. It never makes the answer negative. A wall chart earns its place by being glanceable from where the work is happening, so Zero and Negative Exponents belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Zero and Negative Exponents?
- The Power of a Power Rule, The Product Rule and The Quotient Rule sit alongside Zero and Negative Exponents 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 Product RuleThe Quotient Rule
- Is the Zero and Negative Exponents poster free to download and print?
- Yes. Zero and Negative Exponents 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 Zero and Negative Exponents poster print at?
- Zero and Negative Exponents 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 Zero and Negative Exponents loses nothing.Printing guide
