Part 3 of this series was about the radical, integral, partial derivative, and infinity signs (√ ∫ ∂ ∞). This final math symbols post, Part 4, covers four Greek derived math symbols: Δ ∑ ∏ π (delta, sum, product, and pi). The only constant is Change The uppercase Greek delta symbol (Δ) is used in mathematics to denote a change or difference. Delta, being an [...]
The last post, Part 2, includes comparative symbols, degree, percent, and fraction slash: > < ≤ ≥ ° % and ⁄. This time, in Part 3, I'm covering the radical, integral, partial derivative, and infinity signs (√ ∫ ∂ ∞). Radical The radical ( √ ) is basically a check mark. It has a funny little bit hanging off the top (left) end of the [...]
Part 1 of this series had the basic math glyphs (addition, subtraction, etc.) and some comparative symbols (equal, not equal, approximately equal): + − ± × ÷ = ≠ and ≈. This post, Part 2, includes some more comparative symbols, degree, percent, and fraction slash: > < ≤ ≥ ° % and ⁄. Squinty Eyes >< ≥≤ The greater than (>) and less than (<) [...]
The last series of posts focused on punctuation, with the previous post covering slashes, bars, and brackets. This four part series covers mathematic symbols. It will be fairly limited, since protest posters don't typically use a wealth of mathematic glyphs. However, it will have more than I originally anticipated, since US protests in early 2017 in defence of science and fact featured a wealth of [...]
