Does it matter what order you do your operations in equations with variables on both sides?

Not if you do all the calculations correctly. For example, in an expression such as:3(4 + 5)
the parentheses specify that you should do the addition first. But in an algebraic expression, such as
3(x + 2)
you can't even calculate "x + 2" as long as you don't know the value of "x"; so it might make more sense to divide by 3 (on both sides of the equation, of course), to get rid of the 3. Or you might open parentheses using the distributive property. There are often different ways to manipulate such an expression (or an equation that contains such an expression); if you do everything correctly, you should get the same result in all cases.

∙ 7y agoNo, it does not - provided you follow the BIDMAS/PEMDAS rules.

What is combination of operations on variables and numbers called?
the order of operations
What is the Commutitive property of math?
In math, the Commutative Property refers to operations in which the order of the numbers being operated on does not matter. Multiplication and addition are commutative operations, which may be demonstrated by the algebraic equations "ab = ba" and "a + b = b + a", respectively.
How do you evaluate algebraic expressions?
Replace the variables with the correct values and calculate using the order of operations
Does the order in which you perform operations in a numerical expression matter?
Yes, unless all of the operations are additions, or all of them are multiplication. Otherwise, changing the order will change the result. The order of operations is determined by parentheses, or if none are present, by the PEDMAS sequence.The order in which mathematical operations must be done has the acronym PEDMAS or PEMDAS. PEDMAS or PEMDAS, no matter how you spell it, gives the correct order for mathematical operations: 1. P - Parentheses, 2. E - Exponents, MD - Multiplication and Division, AS - Addition and Subtraction.
How do you use the FOIL technique in Algebra?
FOIL stands for First, Outer, Inner, Last. It is the order of operations to solve equations like (2x+3)(3x+2).
How does the order of operations relate to solving multi-step equations?
The order of operations relate to solving multi-step equations because you are following the order of operations just in a backwards way.
What is combination of operations on variables and numbers called?
the order of operations
What does the E stand for in order of operations?

When do you use order of operations?
You use order of operations in equations that have more than one type of operation going on (for example, an equation with parenthesis, addition, and multiplication). You would use order of operations in equations like that so you know which operation to do first.
Why is it necessary to study order of operations and laws of operations before you solve equations?
Because if you did operations in an impermissible order, or violated laws of operations, then your solution to the equation is wrong.
What is the property of moving around numbers and variables?
order of operations
What is the Commutitive property of math?
In math, the Commutative Property refers to operations in which the order of the numbers being operated on does not matter. Multiplication and addition are commutative operations, which may be demonstrated by the algebraic equations "ab = ba" and "a + b = b + a", respectively.
How do you expressions?
Replace the variables with the given values. Then you calculate using the order of operations.
What is it when you substitute numbers in for the variables and follow the order of operations?
It is evaluating the expression.
How do you solve simultanious equations?
By eliminating or substituting one of the variables in the two equations in order to find the value of the other variable. When this variable is found then substitute its value into the original equations in order to find the value of the other variable.
What is the order of operations for solving math equations?
Parentheses Exponents Multiplication Division Addition Substraction
What are the steps to solving equations?
combine like terms order of operations () 2 X / + - and that's it.
