The same symbol turned upside down (⊥, U+22A5) is used for “false.” An advantage of using this symbol rather than some form of F is that it makes the symmetry of some formulas more apparent. Logic also uses symbols that look like a T rotated 90 ° clockwise or counterclockwise, ...
Certain math symbols, numbers, and answers.Plane Symmetry:If a plane intersects a three dimensional figure such that one half of the figure is the reflected image of the other half, the figure possesses "plane symmetry". The two halves of the figure are mirror images in the plane. Plane sy...
Replace the question mark with mathematical symbols to make this equation work: 7 ? 7 ? 77 ? 7 ? 7 = 497 7 + 77 * 7 – 7 * 7 = 497. A rat is placed at the beginning of a maze and must make it to the end. There are four paths at the start that he has an equal chance...

Another affine game is a game of EvenQuads played on a deck of size 64. Each card has 3 attributes with 4 values each. Each card has symbols of a color (red, yellow, green, or blue), a shape (spiral, polyhedron, circle, square), and a quantity (from 1 to 4). The set, called...
What do the shorthand computer symbols * and / mean in algebra? In math, what does the symbol * represent? In math, what does the following notation represent: \binom nk ? What is the meaning of algebra in math? What do the upside-down question marks indicate in the equation?
In the image below, the green line intersects with the blue line at point A. Intersecting and Parallel Lines Intersecting Lines: Symbols and Meaning There is a special notation used to denote intersecting lines or sets, called the intersection symbol: ∩. Note how the green and red lines ...
Because math and set theory have been around a really long time, we have symbols that are easy to write with pencil and paper. But not so easy to write with typing! Let’s start with one of my fav’s: . That upside down A stands for “for all” or “for every.” If we were ...
