No one knows. It happened before there was any writing, so there is no record of when it happened or who did it. Addition and subtraction are simple enough that many animals can perform it, albeit not quite well sometimes, even in the wild and without training. It is a natural Darwinian skill. For example, crows can count how many lions took down a gazelle behind a bush (out of site) and then count them as they come out again so it knows when it can scavenge freely (they sometimes have trouble with numbers bigger than 3).
Undoubtedly, early humans could add and subtract reasonably well on the hunting grounds on the grasslands of Africa, before language. Multiplication would have come along as humans had more free time to think or calculate and the skill was probably improved on along with war and complicated hunting. Division is more complicated and may have only been used "intuitively" for a long time, until the ancient civilisations and cultures developed better mathematics (likely a Arabic, Egyptian, Mediterranean, Chinese or Indian culture).

Is the set of odd numbers closed under multiplication?
Yes.To say a set is closed under multiplication means that if you multiply any 2 numbers in the set, the answer will always be a member of the set. When you multiply 2 odd numbers, the answer is always an odd number, so the set is closed.It must be the same person asking these questions!Read more: Is_the_set_of_odd_integers_closed_under_subtraction
What multiplication property is used for 53 X's 6 equals 6 X's 53?
Commutative property. To remember what the commutative property does, think of the word: commute.A person commutes to work each day. He changes his position (he's at home, then he's at work).In the commutative property of multiplication, the terms can move around or change position and the result will be the same.
How can you use multiplication to check quotient?
You can use multiplication to check a quotient because, if you think about it, division is like algebra with multiplication.Lets say you have the problem 49/749/7 is 7, right? So you check by taking the answer (7) and the divisor (7) and multiply it to check.Does 7x7=49? Yes, it does!The quotient is right if you multiply the divisor by the quotient and get the dividend.Another example for your benefit:153/3You do the calculations wrong, but you are smart enough to check to find out you did this.Lets say you think that 153/3=13.You check by doing: 13x3.When you are done calculating 13x3, you get 39.BUT you didn't get 39 when dividing.So this proves that 13 IS MOST DEFINITELY NOT the answer.You divide again and get 51.Being the smart person you are, you check that answer.51x3=153By checking, you got it right!

How is math used in accountant?
Accounting includes both basic math and advance math as well.It really depends on what type of math you are talking about.Addition,subtraction,multiplication and division are the basic math calculations. In general, you can still do accounting even if you aren't good at math.Accounting deals with a ton of numbers, but you don't do anything crazy with those numbers. You need to be able to understand them and do some basic calculations with them such as addition, subtraction, division, multiplication, fractions, and percentages. You also need to do some problem solving as accountants face a lot of problems with the numbers on paper.Accounting and math do go hand in hand, but not to the extent people think that they do.
What are facts about numbers?
Numbers are mathematical symbols used to represent quantities and perform calculations. They can be classified into various types including whole numbers, natural numbers, rational numbers, irrational numbers, and complex numbers.

How do you get to human calculator in world maths day?
You have to be very quick and get most the answers right. Once, I got human calculator but it only lasted for a while. Here are some tips:Practise your time tables, division, addition, subtraction with random sums (if you want get a friend/family member to give you a test and see if you improve every weekSet out a chart with the times tables, division, addition and subtraction all mixed up and test yourself every day/every two days, etc.I hope you get human calculator!Yes, yes. What the previous person said is right.I have managed to reach human calculator in 2010, and the sums get harder. You also play 1v1 sometimes, so it makes you really tense!
How do you get 214 in multiplication?
A person can get to 214 in multiplication by multiplying 2 by 107. Multiplication is the process by which one number is scaled by another to produce a greater number.
Who is credited with inventing multiplication?
There was not a single person credited with inventing multiplication. Egyptians, Babylonians, and Chinese all had their own methods. John Leslie invented the multiplication table.
What does x equal in 6-2x divided by 3 equals 5?
The question is a bit ambiguous (what is divided by 3?) because of the limitations of the word processor. Here are two answers for the two most likely scenarios: I. (6-2x)/3 = 5 => 6-2x = 15 => 2x = -9 => x=-4.5 II. 6 - 2x/3 = 5 => 2x/3 = 1 => x = 1.5 Improved: The person above gave you the incorrect answer for part I and II. In algebra or in any math, you need to always do the division first before go to any other operations. You need to follow the guide: Division, Multiplication, Addition, then Subtraction. For your answer, it is I. (6-2x)/3 = 5 Multiply by 3 on both sides 6-2x = 15 Subtract 6 on both sides -2x = 9 Divide by -2 x=-4.5 Answer
What is multipulcation?
multipulcation is a kinda math that you do but it is more difficult than addition or subtraction Multiplication is where you have one number and enlarge that number by another number. Or another way of saying it if you still don't understand is: the first number is added to itself by how much the second number is. by So to make this simpler I'm going to give an example: 6 X 2 = 12 Now think of it as: Multiplication is where you have the number 2 and enlarge 2 six times. It is basically: 2 + 2+ 2+ 2+ 2+2= 12. Multiplication helps make the big problem a now small problem. Hi, not the person who wrote that. It is so you do not have to add something so much. (example) 6*8=48 How? It is just adding 6 eight times. I hope this is helpful!
