When a equation uses addition the variable can be solved by subtraction True or False?
True.
What is always true about whole numbers?
They form a closed set under addition, subtraction or multiplication.
Why do two negatives equal a positive?
That's not necessarily true for addition and subtraction. It's only true for multiplicatioin and division. I look at it this way: "Negative" can mean 'down' or 'not', and 'not down' is the same as 'up'.
What is the acronym for performing arithmetic functions?
The acronym for performing arithmetic functions is "BEDMAS", which stands for Brackets, Exponents, Division, Mutiplication, Addition, and Subtraction. This is the "order of operations" for any arithmetic problem.Note: The French acronym "PEDMAS" - - Parentheses, Exposants, Division, Multiplication, Addition, Soustraction - - corresponds to "BEDMAS".Note: The order of division and multiplication operations may be switched in an arithmetic problem, and the same is true for addition and subtraction.
What is commutative propriety of addition?
It simply means that the order of the addends is immaterial - if 3 + 5 + 7 = 15 then 5 + 7 +3 = 15. This is also true for multiplication, but not for division or subtraction.
What six letters represent the order of operations in math?
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction (remember that multiplication and division occur at the same time starting at the left and moving right and the same is true of addition and subtraction. So the six letters: PEMDAS Which is commonly expressed as Please Excuse My Dear Aunt Sally or Purple Elephants Marching Down A Street.
What is meant when you say that subtraction is the same as addition of the opposite?
here is subtraction problem... 9 - 4 = 5 here is an addition of the opposite 9 + -4 = 5 both these equations are true and mean the same thing. when you subtracted you are actually adding the negative of that number. the negative means to put a minus symbol in front of that number and that number is the amount of units it takes from below zero to get to zero.
Why does the commutative and associative properties don't hold true for subtraction and division but the identity properties do?
Consider the main operations to be addition and multiplication. In that case, subtraction is defined in terms of addition, for example, a - b = a + (-b) (where the last "-b" refers to the additive inverse of b), while a / b = a times 1/b (where 1/b is the multiplicative inverse of b). Now, assuming that commutative, etc. properties hold for addition and multiplication, check what happens with a subtraction. That should clarify everything. For example: a - b = a + (-b) whereas: b - a = b + (-a) which happens NOT to be the same as a - b, but rather its additive inverse.
