Does it matter which way you subtract the values when finding distance when subtracting negative numbers?

The RULES for subtraction do not depend on the signs of the numbers. A - B means the value of A (+ or -) minus the value of B(+ or -). So if A is -1 and B is -2 you have (-1) - (-2). Subtracting a minus is a plus (like taking away a debt). So: (-1)+2 or -1+2 = 1. Think of positives as dollars in your hand, and minuses as bills in your hand you have to pay. If someone takes away a bill, you are better off. Similarly for distances. So it does matter - you must do it properly.

Subtracting one number from another is finding what between them?
That is called the difference between them.
Can you show on a number line how subtracting a negative number ends up positive?
-3...-2...-1...0...1...2...3To find the positive number when subtracting from a (-)number is finding the Absolute Value of the sum. Another way is changing the negative number to a positive and reversing the equation.*Such as, 1-(-3)--> +3-1. So than the answer is a positive 4.* Dots represent the actual line
What is a rule for finding number pairs that add to 100?
One rule for finding number pairs that add to 100 is to start with one number and subtract it from 100 to find the other number. For example, if one number is 75, subtracting it from 100 gives 25, so the pair is (75, 25).
How do you subtract fractions with unequal denominators?
by finding the common denominator of the fractions
How do you add and subtract dissimilar fractiono?
By finding the lowest common multiple of the denominators.
Does deposit mean to add or subtract?
deposit = add withdraw = subtract
How is finding the LCM revelant when adding and subtracting fractions?
To add and subtract fractions, you need common denominators. To find the common denominator, find the LCM of the denominators you wish to add or subtract.
Does it matter which way you subtract the values when you are finding the distance?
Not if you take the absolute value of the answer.
What problems can be solved using gcf and LCM?
Finding the LCM will make adding and subtracting fractions easier.
When you subtract fractions you are finding their?
You are finding their difference.
Do you subtract when finding range?
Yes.
What is the difference between subtracting with regrouping in whole numbers and subraction with regrouping in fractions?
We look at the signs of numbers when we need to combine them. We subtract only if numbers have different signs, otherwise we add them. So that, if we have in an expression several positive and negative numbers, we prefer to group numbers with the same sign and add them in order to subtract just once. While with fractions we like to group fractions with the same denominator first, and after that we can combine all fractions by finding their LCD.
When you subtraction tow numbers?
Subtracting two numbers is finding their difference.
When is it useful to find the LCM or GCF of two numbers to solve a problem?
When adding or subtracting fractions with different denominators and when reducing fractions to their lowest termsWhen adding or subtracting fractions with different denominators their lowest common multiple is needed and when reducing fractions to their lowest terms their greatest common factor is needed.
