it was around the time of christ.
Although the first set of rules for dealing with negative numbers was stated in the 7th century by the Indian mathematician Brahmagupta, it is surprising that in 1758 the British mathematician Francis Maseres was claiming that negative numbers "... darken the very whole doctrines of the equations and make dark of the things which are in their nature excessively obvious and simple" .
Maseres and his contemporary, William Friend took the view that negative numbers did not exist. However, other mathematicians around the same time had decided that negative numbers could be used as long as they had been eliminated during the calculations where they appeared.
It was not until the 19th century when British mathematicians like De Morgan, Peacock, and others, began to investigate the 'laws of arithmetic' in terms of logical definitions that the problem of negative numbers was finally sorted out.
However, there were references to negative numbers far earlier...In 200 BCE the Chinese number rod system (see note1 below) represented positive numbers in Red and Negative numbers in black. An article describing this system can be found here . These were used for commercial and tax calculations where the black cancelled out the red. The amount sold was positive (because of receiving money) and the amount spent in purchasing something was negative (because of paying out); so a money balance was positive, and a deficit negative.Negative intergers were accepted around the time of Christ.

How many integers between 1000 and 9999 have distinct digits?
Distinct means different from all others. So there can be no repeated digits. Thus, 4124 is not possible because there are two '4' digits. There are 9 ways to choose the first digit (1-9, as 0 is not possible). Subsequently, there are 9 choices for the second digit, since there are 10 possible digits (0-9), but we can't pick the same one as the first digit. Next, there are 8 ways to choose the 3rd digit, since we can't choose the same as either of the first two digits. Finally, there are 7 ways to choose the 4th digit. The answer is 9 * 9 * 8 * 7 = 4536.
What is 10 percent less than 250?
Ok, type in 250 into your calculatorNext, multiply by .10 (10% in decimal form)Next, see your total of 25And finally, subtract 25 from 250and you get 225 as your answer.
Why is subtracting a negative number the same as adding a positive number?
The best way to understand this is probably by thinking of the real number line:Subtracting can be thought of as switching directions as you move along the number line. For instance, 5 + 3 means you start at position 5 on the positive side of the number line and move to the right, the positive direction, 3 integral ticks. However, 5 - 3 means you switch directions. Now, you start at position 5 and move left, the negative direction, 3 integral ticks.Negation can be thought of in the same manner as subtraction; i.e. as a directional change on the number line. Using the above example, that would mean that for 5 + (-3) you would once again start at position 5 on the positive side of the number line and start to move right, since that what addition means. However, the negative sign in front of the 3 forces you to change direction, so instead you end up moving left 3 integral ticks.Now, to finally answer your question. 5 - (-3), using the number line, would again mean that you would start at position 5 on the positive side. The subtraction operation, as explained above, means that you would move left 3 ticks instead of right. However, the negation of 3, also explained above, means that you would once again switch directions, this time from left to right, and ultimately move 3 ticks that way, the positive direction. Hopefully, you can see that the end result of both 5 + 3 and 5 - (-3) has you moving 3 ticks in the same direction, that being the positive direction, which is why they can be thought of as the same operation.

When was Pangaea finally accepted as true?
The concept of Pangaea, a supercontinent that existed millions of years ago, was first proposed by Alfred Wegener in 1912. However, it was not widely accepted by the scientific community until the mid-20th century when supporting evidence from paleontology, geology, and plate tectonics emerged.

Why was tomato not originally put on pizza?
When tomatoes were first introduced into Europe in the 16th century, they were thought to be poisonous and were only slowly and gradually accepted on the dinner table. Even in the US, they were considered poisonous. Finally, in the late 18th century President Thomas Jefferson countered that rumor, when he started to eat them. That probably explains the slow acceptance of tomatoes on pizza.

The sum of four consecutive integers is -22 What are the four numbers?
Since the sum is -22, the 4 integers are all negative. I first began with smaller integers. If you choose -4, -5, -6 , -7. The sum is -22. To check, add -4 + -5 + -6 + -7. I am unsure of your level, but there is a way to solve it algebraically. I choose n to be the first number. The next number is also negative, and that will be n - 1. The next number will be n - 2 and then the fourth consecutive integer is n - 3. The sum will be n + (n - 1) + (n - 2) + (n - 3) = -22 4n - 6 = -22 4n = -16 n = -4 Therefore the first number is -4, then -5, -6 and finally -7.
