No, changing order of vectors in subtraction give different resultant so commutative and associative laws do not apply to vector subtraction.

Can you apply the associative property to subtraction?

No, the associative property only applies to addition and multiplication, not subtraction or division. Here is an example which shows why it cannot work with subtraction: (6-4)-2=0 6-(4-2)=4


What are the basic rules of algebra?

The basic rules of algebra are as follows... * Remember when moving a constant from one side to another, you must apply new value. (ie. positive or negative number) 5+x=25/5+5-5=25-5/x=5 You must remember to isolate the unknown value (more commonly known as a variable) in order to solve an equations. 5x+4=x+20/ Group variable on one side, constants on other. 5x-x=20-4/4x=16/x=4 You may only add, subtract, multiply and/or divide coefficients and variables which are the same. (ie.x+x/2x+3x) After you have finished solving your equation, the order of variables are as follows this- alphabetical order, and then its the highest exponent sum. (ie. x+y4+z7) If requested, present a Left-Side Right-Side check. * Commutative property: a+b = b+a, ab = ba * Associative property: a+(b+c) = (a+b)+c = a+b+c, a(bc) = (ab)c = abc * Identities: a+0 = a, 1a = a * Distributive property of multiplication over addition: a(b+c) = ab+ac The first three properties have an versions for addition and multiplication. Division and subtraction are not commutative or associative. The distributive property ties addition and multiplication together. One important concept is the order of operations. Parentheses establish precedence. Multiplication and division occur first, left to right, and then addition and subtraction. Thus, 5+3x4 = 17, not 32. Other key concepts are the slope/intercept form of a line, y=mx + b, where m=slope and b=y intercept. Memorize the quadratic equation--it will prove very useful. And above all else, learn how to do ratios and proportions.


When simplifying an expression you perform which operations inside grouping symbols first?

Within parentheses or similar symbols, the same rules apply as when you don't have parentheses. For example, multiplication and division have a higher priority (or precedence) than addition and subtraction.Within parentheses or similar symbols, the same rules apply as when you don't have parentheses.

When will you apply surds in real life?

You will apply them when solving quadratic equations in which the quadratic expression cannot be factorised.


What is the rules of PEMDAS?

The rules of PEMDAS are 1. Parenthesis anything in them you do first. 2. Exponents those little numbers next to the number telling you to multiply the number by itself a certain number of times 3. Multiplication and Division whichever comes first and 4. Addition and Subtraction whichever comes first. If there is an exponent next to parenthesis but there is no number that means the answer to the parenthesis has to be the thing that the exponent is next to. All of the rules apply inside of the parenthesis as well. If there is a number next to the parenthesis not followed by a symbol multiply the answer to the parenthesis by that number.
