Algebraic expressions are a series of arithmetic operations consisting of the four operations, numbers, variables, parentheses and other mathematical symbols (square roots, powers, factors...).
These algebraic expressions are abstracted from physical concepts so that we can see their applications in all fields.
As we said earlier, algebraic expressions mainly consist of the four operations, numbers, variables, parentheses and various mathematical symbols that we will discuss as follows:
Let's take some exemples:
Sum of two unknown numbers.
Let the first number be and the second number be .
So their sum is
The sum of twice and
Let the first number be , the twice of is .
So the sum is
The difference of the number and the triple of the number .
The variables are already defined and . the triple of is .
So the difference is
The difference of the product of and , and the quotient of and
The product of and is
The quotient of and is
So the difference is
The product of two consecutive numbers.
Let be the first number. then the second number is .
So, the product of this two numbers is
The product of the sum of the numbers and and the sum of the numbers and twice of .
The sum of and is
The sum of and the twice of is
The product is
The sum of the square root of a number and the number next of it
Let the unknown number. then the square root of is . The number next of is . The sum is
