## Arithmetic Glossary

### A

• Addition  -  Finding the sum of two or more munbers.

### C

• Comparison  -  Compasring two numbers to see which is the largest.
• Counting  -  An action to finding the number of elements of a finite set of objects.
• Counting Number  -  Any number used to count things  $$\large{ 1, 2, 3, 4, 5, 6,... }$$  excluding  $$\large{ 0 }$$ , negative numbers, fractions or decimals.

### D

• Division  -  Dividing two numbers to find how many times one number is contained in another number.

### E

• Equation  -  A statement containing one or more variables that are either added, subtracted, divided or multiplied to get an answer.  $$\large{ 13a^2+7x-21=19 }$$

### F

• Fraction  -  A part  $$\large{ \frac{3}{8} }$$  of the whole.
• Factor Number  -  Numbers $$\large{ 3 }$$ and $$\large{ 8 }$$ are factors that can be multiplied to get another number $$\large{ 24 }$$ .  Equation $$\large{ 3 \times 8=24 }$$
• Formula  -  An expression in symbols used to calculate a desired result in mathematics and chemistry.

### M

• Mean  -  The sum of all numbers in a set divided by the number of the values.  $$\large{ (2 + 3 + 4 + 5) / 4 = 3.5 }$$
• Multiplication  -  Adding a number by itself multiple times.
• Multiplier  -  In a set of terms  $$\large{ 3 \times 7 = 21 }$$  the number that you are multiplying by.  $$\large{ 3 }$$  is the multiplier,  $$\large{ 7 }$$  is the multiplicand, and  $$\large{ 21 }$$  is the product.

### N

• Negative Number  -  It is the oposite of a whole number  $$\large{ ... , -5, -4, -3, -2, -1 }$$  or decimal number excluding  $$\large{ 0 }$$ .
• Number  -  A mathmatical object used to count.
• Number Types  - digits, fractional number, integer number, irrational number, natural number, numeral, rational number, real number, transcendental number, and whole number
• Numeral  -  A single symbol to make a numeral like  $$\large{ 2119 }$$ .

### P

• Positive Number  -  A counting number  $$\large{ 1, 2, 3, 4, 5, 6,... }$$  or decimal number excluding  $$\large{ 0 }$$ .

### R

• Rational Number  -  Any number that can be expressed as a ratio (fraction) of two integers numbers.  $$\large{ 0=\frac{0}{1} }$$ ,  $$\large{ 0.125=\frac{1}{8} }$$ , $$\large{ 1.5=\frac{3}{2} }$$

### S

• Subtraction  -  An operation of taking away an amount from another to get a difference.
• Sum  -  In a set of terms  $$\large{ 3 + 7 = 10 }$$  it is the result.  $$\large{ 10 }$$ is the sum, and  $$\large{ 3 }$$  and  $$\large{ 7 }$$  are each addends.

### W

• Whole Number  -  Just positive numbers  $$\large{ 0, 1, 2, 3, 4, 5, 6, ... }$$  with no fractions.
