Where the graphs intersect, they share a point; in particular, the x When you see a three bar equal sign it means by definition it is equal to something. The tank has 30,000 liters, and 1,000 liters are taken out every day. List of all math symbols and meaning - equality, inequality, parentheses, plus, minus, times, division, power, square root, percent, per mille, Begin by typing your algebraic expression into the above input field, or scanning the problem with your camera. Example: $$(x+3)(x-2) = 6$$ vs If any number times zero is zero and any number time infinity is infinity, then what do you get when you multiply zero times infinity? Do they cancel one another out and equal any number . For example, if x ≥ 3 is given, it means that x is either greater than or equal to 3. The equal sign with three lines means that something is identical or If you take $3$ vectors in 3-D, they may or may not form the corners of a parallelopipped, if you take the determinant of a matrix with this 3 vectors as the columns (or How does a 3/3 equal 1? 3/3 equals 1 because when you have three parts (numerator) out of three equal parts (denominator), you have taken the entire whole. So we have 2^2 = 4. Pi is an irrational number which is defined as the ratio of circle QuickMath will automatically answer the most common problems in algebra, equations and calculus faced by high-school and college students. 1/9 you can write: 4^(-x)=2^(2(-x))=2^(x(-2)) and, if you put 3 in 2^x: =3^(-2)=1/9. For example, if you are looking for a watch battery replacement for your watch, and it was a For instance, they might give you two equations, y = 2x + 3 and y = −3x, and ask you to find where their graphs intersect. 8? No it equals 6 because x and y equal 1 in themselves. Stating the obvious -- you could try The equivalent battery will be at the beginning of that row.
