How is subtracting fractions different from adding fractions?
In subtraction you take away rather than add. Also, addition is commutative, subtraction is not so the order of the numbers does matter for subtraction.
Does the order of the numbers matter when subtracting three different numbers?
If only 1 operation is happening, always go from left to right. it does matter with subtraction.
Does it matter when using subtraction the order in which the numbers are presented?
Yes it matters. Subtraction is not commutative. Example: 5-2 = 3 (positive three), but 2-5 = -3 (negative three)
What does commutative property of addition mean?
It means that it doesn't matter what order the numbers you are adding are in. A plus B is the same as B plus A. Contrast it with subtraction which does not have this quality.
What is 15-5 plus 9 - 2 in PEMDAS order?
Pemdas says that addition and subtraction can be done in any order, so it doesn't matter. 15 - 5 = 10 10 + 9 = 19 19 - 2 = 17 The answer is 17. Pemdas- Parentheses, Exponents, Multiplication/Division, and Addition/subtraction. The slashes mean that those two can be done in any order, and you will get the same answer/

Why is there no commutative property for subtraction or division?
There is no commutative property in subtraction or division because the order of the numbers cannot be change. This means that when multiplying or adding it does not matter the order of the numbers because the answer comes out the same.

Which calculations come last in the order of operations?
addition and subtraction

Do you move the decimal in subtraction?
No, you don't move the decimal in subtraction. However, you may need to add trailing zeroes after the decimal in order to make subtraction easier.
Is the order of subtraction in the slope formula important?
Yes

Do the commutative and associative laws apply to vector subtraction?
No, changing order of vectors in subtraction give different resultant so commutative and associative laws do not apply to vector subtraction.
What is the last step in the order of operations?
Subtraction. Remeber it's PEMDAS. Parenthesis, Exponent, Multiplication, Division, Addition and Subtraction.
Do you add before you subtract?
In mathematics, the order of operations dictates that you perform addition and subtraction in the order they appear from left to right in an expression. This means that you should perform addition before subtraction only if addition comes before subtraction in the expression. If addition and subtraction are next to each other, you would perform them from left to right.
