Integers are represented as a string of 1's and 0's. The bits (a single one or zero) are weighted by powers of two, so the one on the far right has value 20 or 1, the second is 21 or 2, third is 22 or 4, 4th is 8, 5th is 16, etc. An integer in a modern computer is typically 32 bits long, or 4 bytes (a byte is 8 bits).
Negative numbers are represented in two's complement form, which is a little complicated to explain here, but if you Google it there are good websites. The reason that 2's complement form is used versus simpler sign-magnitude are that it makes the math easier for a computer's processor.
The set of integers is represented by Z.
It can be represented as a ratio of two integers.
Zero
It comes from the German word zahlen.
They are negative integers.
They can be represented as a fraction of two integers.
Motion can be represented through equations that describe the change in position over time, such as the equations of kinematics in physics. In computer graphics, motion can be represented using keyframes or motion capture data. In the field of animation, motion can be represented using timelines and keyframes to animate characters and objects.
They both describe integers.
2 power n
They can all be represented by ratios of two integers.
No. 1.75 is NOT an irrational number. Rational numbers cannot be represented as a ratio of two integers. 1.75 can be represented as a ratio of the integers 175 and 100, i.e. 175/100 Note that this can be reduced to the equivalent fraction 7/4, which is a ratio of the integers 7 and 4
No - because it can be represented as a ratio of integers : 10 = 10/1 Any number that can be represented as a ratio of 2 integers is classified as a rational number (other than that you can't use 0 for the denominator)
