Basic Math Operations
Parts of Equations
We will be looking at various math operations such as addition (+), subtraction (-), multiplication (x), and division (÷). Let's briefly discuss the parts of addition and subtraction equations.
Addition
An easy addition equation may look like this -
7 + 3 = 10
addend + addend = sum
The numbers 7 and 3 are called "
addends".
The answer is called the "
sum".
10 is the sum of 7+3.
The Equal Sign
The equal sign (=) says that what is on the left of the sign is equal to , or the same amount as, what is on the right of the sign.
Let's look at the equations
6 + 1 = 10 -3 and 6 + 1 = 3 + 4
7 7 7 7
The
amounts on either side of the equal signs are the same. Can you see how I could have written many more equations?
Subtraction
An easy subtraction equation may look like this -
10 - 6 = 4
minuend - subtrahend = difference
The 10 is the first number and it is called the "
minuend". It is usually the
greatest number.
The number after the minus sign is called the "
subtrahend". In this case it is the number 6. It is
usually less than the minuend, but can be the same as the minuend.
The answer is called the "
difference".
The difference between 10 and 6 is 4.
