Which operation is the first step to evaluate 3 times 2 to the fourth power plus 25 divided by 5?

Stating the problem in words causes some ambiguities. I will assume you mean 3 x 24 + 25/5. First do the power. Replace the value before proceeding. Then do the multiplication and the division. Replace the values. Finally do the sum.
In general, you should first do the powers, from right to left. Then do all multiplications and divisions, from left to right. Then do additions and subtractions, from left to right. If there are parentheses, do anything within parentheses first. Anything in an exponent (in a power) should be done first - 25+3 implicitly means 2(5+3). A horizontal line in a fraction also causes implicit parentheses:
1+2
-----
3+4
implies two pairs of parentheses: (1+2) / (3+4).

How do you evaluate a math expression?
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.
Does it matter in which order we do each operation?
Yea because the collection of rules that define which procedures to perform first order to evaluate a given mathematical expression.
What is a set of rules for evaluating an expression involving more than one operation?
First evaluate all powers. Then evaluate multiplications and divisions, from left to right. Then evaluate additions and subtractions, also from left to right.Parentheses change the order of operations: you must evaluate anything in parentheses first, before combining it with anything outside the parentheses. Within the parentheses, the first rule also applies (first evaluate powers... etc.).Parentheses can be implied in some cases. For example, in fractions, you have to evaluate the numerator and the denominator separately, before carrying out the division of numerator / denominator. Also, in the case of powers, e.g. 25+3, the exponent has to be evaluated before the power. In the example, you add 5+3 before calculating the power.
What is the median of first seven prime number?

What is an agreed set of rules to evaluate numerical expression?
The usual rules are: * Evaluate anything within parentheses first. * Evaluate multiplications and divisions from left to right. * Then evaluate additions and subtractions from left to right.

What is the order of operation performed in a fraction?
To Evaluate expressions using the order of operations where there are fraction bars, simplify the top and bottom first, then divide.

What is an proportion?
a proportion is a relation of four quantities such that the first divided by the second is equal to the third divided by the fourth. in other words, it is a way to find equal fractions or ratios.
To evaluate a variable you must values for the variable and then calculate the result?
No. To evaluate a variable, you simply take its value. When you assign a value to a variable, the evaluation of that operation is the value of the variable after assignment. There is no calculation required to evaluate a variable, unless that calculation is part of the right-hand operand of an assignment operation, in which case the calculation is evaluated first and the result of that evaluation (the value) is then assigned to the variable which is then evaluated.
What is a set of rules used to evaluate expression with more than one operation?
order of operations:);evaluate powers first, parenthesis second, multiplication and division third (if there is a combination of the two it doesn't matter the order you evaluate), and addition and subtraction last (like multiplication-division it doesn't matter the order you evaluate these two, a helpful tool for this step is to change all minus operations to plus negative).

What is the answer in devision?
Division is a mathematical operation where a number is divided by another number to find out how many times the second number is contained within the first number. The result of a division operation is called the quotient.
