Example Question #1 : How To Add Odd Numbers
If and
are odd integers, and
is even, which of the following must be an odd integer?
Even numbers come in the form 2x, and odd numbers come in the form (2x + 1), where x is an integer. If this is confusing for you, simply plug in numbers such as 1, 2, 3, and 4 to find that:
Any odd number + any even number = odd number
Any odd number + any odd number = even number
Any even number x any number = even number
Any odd number x any odd number = odd number
a(b + c) = odd x (odd + even) = odd x (odd) = odd
Example Question #1 : Even / Odd Numbers
At a certain high school, everyone must take either Latin or Greek. There are more students taking Latin than there are students taking Greek. If there are
students taking Greek, how many total students are there?
If there are students taking Greek, then there are
or
students taking Latin. However, the question asks how many total students there are in the school, so you must add these two values together to get:
or
total students.
Example Question #1 : How To Subtract Odd Numbers
Assume and
are both odd whole numbers and
.
What is a possible solution for
An odd whole number minus an odd whole number will result in an even whole number. Since , the subtraction will result in a negative even whole number. The only answer that fits these requirements is
.
Example Question #2 : How To Subtract Odd Numbers
Choose the answer below which best solves the following equation:
If you have trouble with problems like this, try stacking the numbers, and subtracting one place at a time. First, seven minus one is six, so that's your ones digit. Next, three minus three is zero, so that's your tens digit. Seven minus two is five, so that's your hundreds digit, and finally, one minus zero is one so that's you're thousands digit.
