- Remember to Practice Order of Operation for the Test Next Class!
- Why do we have to know math? I don't like it!
- Okay! Yeah! Lets go!
- Don't worry, I'm really good at math I'll help you!
- Hey, look!What's That?
- Don't know.Let's go check it out!
- Come over! Its a treasure chest!
- There's a note!
- What does it say?
- SOLVE THESE EQUATIONS TO OPEN CHEST:15-(2*5-4)=15-(6*2)+2=(23-(8*2))-5=
- Great. Math. Guess we wont find out what's inside
- Don't worry! We can solve It together.Lets start with the first one!
- 15 - ( 2 * 5 - 4 ) = First you do what's inside the parentheses(2 * 5 - 4 ) There's multiple steps here. Be careful !We start of by doing the multiplication first2 * 5 = 10Now that we've solved the first part lets do the subtraction !10 - 4 = 6
- There's Multiple Steps Here. Be Careful!
- 15 - ( 2 * 5 - 4 ) = Yay! We are almost there!Now that we have finished what's inside the parenthesis lets work on what's on the outside.15 - 6 = 9The first number to open the lock is 9
- Remember Order of Operations is Very Important!
- Let's do the next one!
- That wasnt so hard
- Yeah!
- 15 - ( 6 * 2 ) + 2= Lets start by doing what's inside the parenthesis6 * 2 = 12 For the next step it's important to remember that just because addition comes before subtraction in PEMDAS it does not mean we do addition first. We do addition and subtraction from left to right. The same applies to multiplication and division.
- P E M D A S
- 15 - ( 6 * 2 ) + 2 = For that reason the next step is 15 - 12 = 3Finally we solve 3 + 2 = 5The second number to open the chest is 5
- You Got This !
- yeah! we got one more!
- That one hurt my brain!
- That one was a little bit tricky!
- Thats okay. But did you understand it?
- ( 23 - ( 8 * 2 ) ) - 5 = There's two parenthesis in this one !Lets start with the one all the way on the inside.8 * 2 = 16Since there is no more to work out inside this parenthesis lets work on the other one !23 - 16 = 7
- ( 23 - ( 8 * 2 ) ) - 5 = One more step and we get the last number to open the chest! We got this.7 - 5 = 2The last number to open the treasure chest is 2
- the numbers are9 5 2
- I got it! It clicked!Lets open it
