42

Since you have 5 cards, there's 5! ways you can arrange them which is 1*2*3*4*5 = 120. But we're not going to list all 120 ways and eliminate those that don't match. The first criteria indicates that the last digit will be 1, 3, or 5. The second criteria indicates that the first digit will be 3, 4, or 5. The middle 3 digits don't matter. So all we need to do is enumerate what combination of 1st and last digits, then multiply by 6 (3!). So let's try them out

Starting with 3 has only 2 possibilities.
3xxx1
3xxx5

Starting with 4 has 3 possibilities
4xxx1
4xxx3
4xxx5

Starting with 5 has 2 possibilities.
5xxx1
5xxx3

So there is a total of 7 different combinations of first and last digits that will satisfy the criteria. And with the 3 left over cards for each combination you can arrange them in 3! ways or 6. So 7 times 6 is the number of different numbers you can make, which is 42.  <span>Douglas Adams would be so proud.</span>

Adding Integers

If the numbers that you are adding have the same sign, then add the numbers and keep the sign.

Example:

-5 + (-6) = -11

Adding Numbers with Different Signs

If the numbers that you are adding have different (opposite) signs, then SUBTRACT the numbers and take the sign of the number with the largest absolute value.

Examples:

-6 + 5= -1

12 + (-4) = 8

Subtracting Integers

When subtracting integers, I use one main rule and that is to rewrite the subtracting problem as an addition problem. Then use the addition rules.

When you subtract, you are really adding the opposite, so I use theKeep-Change-Change rule.

The Keep-Change-Change rule means:

Keep the first number the same.

Change the minus sign to a plus sign.

Change the sign of the second number to its opposite.

Example:

12 - (-5) =

12 + 5 = 17

Multiplying and Dividing Integers

The great thing about multiplying and dividing integers is that there is two rules and they apply to both multiplication and division!

Again, you must analyze the signs of the numbers that you are multiplying or dividing.

The rules are:

If the signs are the same, then the answer is positive.

If the signs are different, then then answer is negative.

If a square has a perimeter of 40 yards, what is the length of one side of the square?

10 yards because a square has 4 sides and all four sides are equal and so 40 divided by 4 equals 10
