That's called an "operator", for example, the plus sign in 3 + 4. The numbers are the "operands" - that is, the numbers (or expressions) operated upon. More precisely, a binary operator, since it works with two operands. In theory, an operand is just a special way of writing a function, since a third number is calculated, according to certain rules, from the other two.

algebraic expressions
When two expressions are equal then it is an equation. This is indicated by putting an equals sign between them.So, for example, all of the following are equations:2 = 22 + 3 = 52x + 3 = 4y - 7For comparison, if the statement contains a less-than or greater-than symbol, it is an inequality, even if it also has an equals sign. Here are some examples:2 + 3 < 72x >= 3y
It is a desimol (2.3)...
the square root symbol. that would make it 1,/2 (i don't know how to make a square root symbol, sorry) but since the numbers are next to each other it is assumed that they are being multiplied and the square root of 2 is approximately 1.414 right in between 1 and 2 :)
You have an inequality.

"less than or equal to". The symbol for less than is " < " and for less than or equal to it is < with a line under it
Sum of is a grouping symbol. 7*(2+5)
A Decimal Point.
Decimal point, giving 1.2
Numerical Expression: 1.) 20+2-8 ( Or any other number with two symbols on math ) Algebraic Expression: 2.) h x 2 ( Or any other number using only one symbol an a letter ) The difference between a numerical and algebraic expressions is that numerical expressions use only numbers, but algebraic expressions use letters as variables to represent numbers.
It is: 2<3 which means the numbers are greater than 2 but less than 3 as for example 2.5
The symbol you are referring to is likely the "caret" symbol, which is commonly used to indicate exponentiation in mathematical expressions. It is not a standard mathematical notation for representing the number Pi.
It is placed between 1 and 2
