In solving an equation with more than one operation you must first add then divide?

Multiplication and division come first, then addition and subtraction. For example:
4 + 2 X 3 + 6 = 16 First you multiply 2 X 3, to get 6, and then you add them, left to right 4 + 6 + 6 = 16. The answer IS NOT 54 and the answer IS NOT 30. The same rule applies with division; division comes before addition or substraction. If there is both division and multiplication and/or addition and subtraction, you resolve the multiplication and division left to right first, then resolve the addition and subtraction left to right.
It is generally better to user parentheses to illustrate exactly what you mean. For example, the above equation would be easier read if it was written 4 + (2 X 3) + 6. Or, if you really had wanted the addition first, (4 + 2) X (3 + 6). Then it is quicker and easier for the reader to see what is going on in equation.

What is the first step in solving a problem in stoichiometry?
Balance the number of atoms for each element on both sides of a chemical equation
What is the balanced equation for phosphoric acid and potassium hydroxide?
When solving this type of problem, first use the ion charges to predict the formulas of the products. Then use coefficients to balance the equation. H3PO4 (aq) + 3 KOH (aq) --> K3PO4 (aq) + 3 H2O (l)
What is the equation you use to find out what you need in the final to get a certain grade in the class?
First you must collect all the papers that were graded. Then you must add up all your grades. After you divide your answer by the number of graded papers you have. This process is called finding the mean or the average.
When writing a chemical equation what must be written first?
First write down what you know. Reactants go on the left, followed by an arrow, with products on the right. Balance the equation.
What steps must be performed before any stoichiometry problem is solved?
Step By Step on solving means breaking down a math problem. For example, if you need to find the square root of 12-3, you would need to do the first step and solve 12-3, then go to the next step of what you were asked.
What is the first step in solving an equation with a variable?
The first step in solving an equation with a variable is doing the inverse operation. For example:4x + 8=32The first step would be to subtract 8 from 32. Since the operation is addition you would do the inverse which is subtraction. Then you would go on to divide 24 by 4Because 32-8= 24 Then you would get an answer of x=6 This answer is correct because 6 multiplied by 4 is 24
What is the first step to solving the equation 6n-2 equals 22?
add 2 to 22, then divide by 6. n= ? n= 4
Which step would not be a possible first step for solving the following equation algebraically?
The first step not possible in solving an equation algebraically is not to provide an equation in the first place in which it appears to be so in this case.
When dividing to find the number to make the statement true which do you divide first?
That depends on the specific situation. If you are solving an equation, and you divide one side by a certain number, you need to divide the other side by the same number.
What is the first step in solving the equation 7q plus 9 equals 3?
the first step in solving the equation is to subtract the nine from the three. you will get negative 6.
What is the first step in solving this equation by completing the square?
The first step would be to find the equation that you are trying to solve!
What are the different steps in solvingradical equation?
The first step is produce the radical equation that needs solving.
Is the first calculation in the order of operation is negation?
No. It is solving brackets or parentheses.
How would decide what to do first when solving an equation involving fractions?
Eradicate the fractions.
How would solving a literal equation differ from a one or two step equation?
The difference is that first you have to understand the problem and translate it into an equation (or equations).
When solving an algebraic equation which operands do you perform first?
In algebra, you perform the operations inside parentheses first.
What is the first step in solving an equation using logical sequencing?
Combine like terms
