# Mathematical formulas

Many universities stress the importance of studying mathematics during computer science courses, mainly in the first year. The point is simply not to make students learn something difficult and perhaps, somewhat boring but to give them the ability to use the universal language of mathematics, without which computer science could not exist. So, why not to learn mathematical formulas in English to enable you to use them in the global world of science?

## Formulas

 1 $a+b$ a plus b, addition 2 $a-b$ a minus b, subtraction 3 $a*b$ a multiplied by b, multiplication 4 $a/b$ a divided by b, division 5 $\neg a$ not a 6 $a \wedge b$ a and b 7 $a \vee b$ a or b 8 $a \perp b$ a is perpendicular/orthogonal to b 9 $a \parallel b$ a is parallel to b 10 $a \in B$ a is contained in B 11 $a^2$ a squared, a raised to the second power 12 $a^x$ a to the power of x, a raised to the xth power 13 $a \leq b$ a is less than or equal to b 14 $a > c$ a is greater than c 15 $2x+4=8$ 2 x plus 4 equals /is equal to 8 16 $2/8 = 1/4$ 2 over 8 equals 1 over 4 17 $\mid -5 \mid = 5$ the absolute value of -5 equals 5 18 $\log_a b=c$ the logarithm of b to the base a equals c 19 $A \supset B$ A includes B, B is a subset of A 20 $\forall x \in A x \in B$ for all x in A, x is in/lies in/is contained in B 21 $\sqrt[n]{a}$ $\sqrt{a}$ $\sqrt[3]{a}$ the nth/square/cube root of a 22 $a_n$ a sub n
