1. Let's start by stating the problem: You want to understand common math symbols and what they mean. 2. Here are some common math symbols with their meanings: - $+$ means addition. - $-$ means subtraction. - $\times$ or $\cdot$ means multiplication. - $\div$ or $/$ means division. - $=$ means equals. - $\neq$ means not equal to. - $<$ means less than. - $>$ means greater than. - $\leq$ means less than or equal to. - $\geq$ means greater than or equal to. - $\infty$ means infinity. - $\sqrt{}$ means square root. - $\sum$ means summation (sum up terms). - $\int$ means integral (area under curve). - $\forall$ means "for all". - $\exists$ means "there exists". 3. These symbols form the basic language in math to express operations, relations, and concepts. Final answer: The symbols represent operations or relations used universally in mathematics to form expressions and equations.
