## Resource summary

Chapter 3
1 Multiplying and Dividing Numbers w/ Intergers
1.1 Multiply - You have to plus the integers together, DO NOT times them, that's for brackets.
1.1.1 3 to the power of 2 x 3 to the power of 3 = 3 to the power of 2+3 = 3 to the power of 5 = 243
1.2 Divide - You have to subtract the integers, then you figure it out
1.2.1 3 to the power of 3 / 3 to the power of 2 = 3 to the power of 2 - 1 = 3 to the power of 1 = 3
1.3 Anything to the power of 0 is 1
1.4 If you have a negative number but the power is even, it equals a positive number (take out the doubles)
1.4.1 If you have negative number without brackets but the power is odd, it equals a negative number
2 Adding and Subtracting Numbers w/ Integers
2.1.1 3 to the power of 2 + 4 to the power of 2 = (3 x 3) + (4 x 4) = 9 + 16 = 25
2.2 Subtracting - Figure out the numbers, then subtract the first second number from the first number
2.2.1 4 to the power of 2 - 3 to the power of 2 = (4 x 4) - (3 x 3) = 16 - 9 = 7
3 Integers with Fractions
3.1 If you have a fraction with no brackets but next to the numerator, denominator or both you have a ingterger, you figure out the number and if the denominator turns out bigger than the numerator, turn it into a mixed number
3.2 If you have brackets and the integer if next to the brackets, it occurs to both the denominator and numerator, you just figure both of them out
3.3 If you have brackets and a integer outside the brackets and also next to the numerator or denominator, you times both integers together and then work out the final answer
3.4 If you have a denominator that is negative you can switch it by multiplying it by -1
4 Integers with Decimals
4.1 If you have a decimal with a integer, you simply figure out normally
4.2 If used in dividing or multiplacation, you times by ten and figure it out using multiplacation, or long division
5 Adding and Subtracting w/ Negative Numbers
5.1 If you have the same sign (- and - or + and +) it equals a positive number
5.2 If you have different signs ( - and + ) it equals a negative number
