Question

whar are variables in algebra not spam​

Answer 1

Answer:

Variables in algebra are letters such as x, y, v, g, or call it any letter you want, that can be used to represent unknown numbers. Basically, whenever we do not know the value of a number, we use a variable until we figure out what the number is

Answer 2

Answer:

$\Huge{\bold{\mathrm{\underline{\red{ANSWER}}}}}$

A variable is a letter used to stand for a number. The letters x, y, z, a, b, c, m, and n are probably the most commonly used variables. The letters e and i have special values in algebra and are usually not used as variables. The letter o is usually not used because it can be mistaken for 0 (zero).

For addition: sum, more than, greater than, increase

For subtraction: minus, less than, smaller than, decrease

For multiplication: times, product, multiplied by, of

For division: halve, divided by, ratio.

To evaluate an expression, just replace the variables with grouping symbols, insert the values given for the variables, and do the arithmetic. Remember to follow the order of the operations: parentheses, exponents, multiplication/division, addition/subtraction.
