My Math Portfolio By: Carina V

Unit 1 In unit 1 I learned how to do the value of power

Example of value of power 8x8x8x8= 8x8= 64 64x8= x8=4096 Final answer = 4,096

Unit 2 In unit 2 I learned how to multiply fractions

Example of multiplying fractions 5/8 x ½= First you see if you can cancel out any numbers. But you can’t so first up we are going to multiply across. Which is 5x1= 5 Then it’s time to multiply across again but on the bottom. Which is 8x2=16. Then the answer is 5/16 but you can simplify. How many times does 5 go into 16? Three times. The remainder is 1. then you keep the same denominator. So the simplified answer is 3 1/16

Unit 3 In unit 3 I learned how to evaluate an expression

Example of evaluating an expression Evaluate the expression when p=24 and q=8 p/q= So first lets plug the numbers into the letters P= 24 and Q=8 So 24 /8 is the equation 24/8 = 3! So 3 is the final answer

Unit 4 In unit 4 I learned how to find the area of a triangle

Example of finding the area of a triangle

Unit 5 In unit 5 I learned how to do ratios. All you do is count how many dogs there are and cats!

Example of ratios Find the ratios of dogs to cats

Unit 6 In unit 6 I learned how to add and subtract integers!

Example of adding and subtracting integers -8+7=? So first you are going to want to see if the first number is positive or negative. It’s negative. So doing this with negatives is pretty much += - and -=+ So it’s pretty much doing -8-7! So the answer is -1!

Unit 7 In unit 7 I learned how to do some Algebra!

Example of Algebra Which expression is equivalent to 8(x+3) A 8x+3 B 8x+24 C 8x+11 D x+24 So first you are going to do distributive property. It’s pretty much doing 8x So what is the answer? Correct B!
