What are counting numbers?

Counting Numbers are Whole Numbers, but without the zero. Because you can’t “count” zero. So they are 1, 2, 3, 4, 5, … (and so on).

First 10 counting numbers are 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10.

To put numbers in order, place them from lowest (first) to highest (last). This is called “Ascending Order“.

A positive integer: 1, 2, 3, 4, … (OEIS A000027), also called a natural number. However, zero (0) is sometimes also included in the list of counting numbers.

Natural numbers are all numbers 1, 2, 3, 4… They are the numbers you usually count and they will continue on into infinity. Whole numbers are all natural numbers including 0 e.g. 0, 1, 2, 3, 4…

Two integers that lie the same distance from the origin in opposite directions are called opposites. For example, “negative 5” is the opposite of “positive 5.” Every number on the number line also has an absolute value, which simply means how far that number is from zero.

Standard numbers, anything greater than zero, are described as ‘positive‘ numbers. We don’t put a plus sign (+) in front of them because we don’t need to since the general understanding is that numbers without a sign are positive. Numbers that are less than zero are known as ‘negative’ numbers.

Positive numbers are written with no sign or a ‘ ‘ sign in front of them and they are counted up from zero to the right on a number line. Any number below zero is a negative number. Negative numbers are always written with a ‘ ‘ sign in front of them and they are counted down from zero to the left on a number line.

The ‘+’ sign Example +65, +0.

In mathematics. 6 is the smallest positive integer which is neither a square number nor a prime number. Six is the second smallest composite number; its proper divisors are 1, 2 and 3. Since six equals the sum of its proper divisors, six is the smallest perfect number, Granville number, and.

So, numbers like 34, π, 3, 8.

When you multiply a negative by a negative you get a positive, because the two negative signs are cancelled out.

Rule 1: A positive number times a positive number equals a positive number. This is the multiplication you have been doing all along, positive numbers times positive numbers equal positive numbers. For example, 5 x 3 = 15.

If two positive numbers are multiplied together or divided, the answer is positive. If two negative numbers are multiplied together or divided, the answer is positive. If a positive and a negative number are multiplied or divided, the answer is negative.

RULE 3: The quotient of two negative integers is positive. If the signs are different the answer is negative. If the signs are alike the answer is positive.

The quotient is the answer to a division. One of the properties of 0, is that 0 divided by any number is 0. The exception is 00 which is undefined. (the fact that 0 is being divided by a negative number makes no difference.

The product of a negative number and 0 is 0. The quotient of a negative number and 0 is undefined.

When you divide a negative number by a positive number then the quotient is negative. When you divide a positive number by a negative number then the quotient is also negative. When you divide two negative numbers then the quotient is positive. The same rules hold true for multiplication.

The number used to divide the dividend is called the divisor, and the answer to the division problem is called the quotient. The numbers being divided may have different signs — either positive or negative. … The first rule is that if you divide two positive numbers, the answer will always be a positive number.

The rule for multiplying and dividing is very similar to the rule for adding and subtracting. When the signs are different the answer is negative. When the signs are the same the answer is positive.

Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. … This would read “negative two minus negative 4”.

Subtracting a number is the same as adding its opposite. So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.
