The algebraic expression for "4 decreased by the quotient of a number and 7" can be represented as 4 - (x/7), where x is the variable representing the number. The expression first calculates the quotient of the number and 7 by dividing x by 7, and then subtracts that quotient from 4. This expression captures the mathematical operation described in the question.
The expression for the calculation 60 divided by 5 added to 11 is (60 ÷ 5) + 11. First, you perform the division operation which is 60 ÷ 5 = 12. Then, you add 11 to the result of the division, which gives you 12 + 11 = 23. So, the final expression simplifies to 23.
use PEMDAS this is called the order of operations and is an acronym. here is what is stands for P=Parenthesis E=Exponents M=Multiplication D=Division A=Addition S=Subtraction You have to do whatever is in the parenthesis first then go onto the exponents... then go to the next operation until all things are simplified. Then you can isolate you variable and find the value of it in the expression.
Expressions within parenthases (brackets) should be done first. Then each operation should be done in turn from left to right. Therefore 4+7x(5+4) would be 4+7x9 and then 11x9 =99.
There is no known origin of the order of operations or PEMDAS. PEMDAS is considered as the proper way to tackle a given mathematical expression in terms of what operation should be performed first.
parentheses
We'll answer this generally, since you haven't provided an expression. A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".

The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
It assures that whatever operation is contained within the parentheses will be carried out first.
Multiplications and divisions from left to right.
In Evaluating Expression first,replace each letter in the expression with the assigned value. second,perform the operations in the expression using the correct order of operations and the last you got the answer

In a standard calculation it would be the exponent, also known as the power of. However, the use of brackets can change the order of operations and so sometimes another operation could be done first. Exponents should be processed first, then multiplication and division, then addition and subtraction. The use of parenthesis brackets can be used to override this default precedence order.
