# What is the multiplication rule?

001 ###### 2013-03-11 15:47:52

States that to determine a probability, we multiply the probability of one event by the probability of the other event.

Ex: Probability that two coins will land face heads up is 1/2 x 1/2 = 1/4 .

THEY HAVE DIFFERENT RULES!!!answered by : REYMIAN  "and" means multiplication "or" means addition The rule says that you can change the order of multiplication: a x b = b x a. For example, 3 x 5 is the same as 5 x 3. There is no rule other than that the order is unimportant for multiplication. xyz is the same as zyx and so forth. For example, 1 * 2 * 3 = 3 * 2 * 1 = 6. The precedence rule PEMDAS which is a mnemonic for Parentheses Exponentiation Multiplication Division Addition Subtraction The rule(s) depend on whether you are looking at multiplication/division, addition or subtraction.  um well i think its about how the problem is and how its written M.D.A.S rule in Mathematics. Multiplication Division Addition Subtraction. MDAS is order of operation.  Rule: product means multiply or multiplication19 * 273 = 5187 Number order in multiplication does not matter, this is known as the associative property. So this means (1*2)*3 = 1*(2*3) Remember the memory reminder of BIDMAS which is the order of operations in arithmetic meaning Brackets, Indices, Division, Multiplication, Addition and Subtraction. Because that is a rule mathematicians agreed upon many years ago. The rule is to evaluate terms according the following order of priority: In UK it is BIDMAS, an acronym for Brackets, Index, Division, Multiplication, Addition and Subtraction. In US, it is PEMDAS = Parentheses, Exponent, Multiplication, Division, Addition and Subtraction order of the mathematical order of operations." Note, that multiplication and division have the same priority; also, addition and subtraction have the same priority. Any number ending with 0 or 5 is a multiple of 5 except 0 itself.   Remember the golden rule: BIMDAS. If you haven't heard it before B means bracket, I means indices, M means multiplication, D is division, A is Addition and S is subtraction. So to answer your question multiplication comes before addition. An exponent of 1 can be ignored. In the same way that multiplication by 1 can be ignored.    The rule is: "The product of zero and any number is zero." If the rule has a name, other than "The multiplication table of zero", I've never heard it.
