## PEMDAS

Can you write me an equation one way and change the solution by adding or taking out parentheses? Show it both ways with the answers. Work it out step by step and line by line just like we do in class. Make sure to put your first name at the end of your post. Be sure to show EVERY step!

Example:  6*10+4=64                or               6(10+4)=84
60+4=64                                      6(14)=84

6. 9(9-4)+2=47

9-5+2x9=54. Sean malone

7. 8*6+3=51 OR 8(6+3)=72
48+3=51 8(9)=72

- Sudeep

8. 2(5+4)=18
2(9)=18 1st example

2*5+4=14
10+4=14 2nd example

9. The top one is Anshul's.

10. 5*(10+2)=60 OR 5*10+2=52
5*12=60 50+2=52

1. Top one is by Anika

11. 15\5+2 OR 15\(5+2)
3+2 15\7
5 2r1
Andrew

12. 9*(7+3) or 9*7+3
9*10 63+3
90 66

13. The one above is from Bryan not Alex I did it at school and it was on Alex's acount

hi

14. (20 + 4) * 9 = 216 or 20 + 4 * 9 =56
24 * 9 20 + 36
216 56
Alison

15. 6*4/2+9=21 OR 6*4/(2+9)=2r2
24/2+9 6*4/11
12+9 24/11
21 2r2
--------Angela--------

16. 48/(2*2*2)+24 OR 48/2*2*2+24
2*2=4*2+8 48/2=24
48/8=6 24*2=48
6+24=30 48*2=96
96+24=120

17. 5*7-6 5(7-6)
35-6=29 5*1=5

21. in a problem you use PEMDAS when your doing alegabra
103 - ( 8 x 7 )
103 - 56
103 - 56 = 56
you always do parenthesis then exponents then multiplication then addition then subtraction - emma

22. 10x5+3=53
50+3
53

10x(5+3)
10x8
80
Lex

23. 1) 2)
2(5*2)=12 2*5*2
5*2=10 2*5=10
10+2=12 10*2=20

24. I made a mistake. The first two rows are example 1 and the last row is example 2.

25. 9*3+(3+4)=34. 9(3+3)+4=58 Eshan

26. 7*10+(10*3). 7*10+10*3
7*10+(30). 70+10*3=240
70+30=100. Or.

27. 6+4*1-5*3-2=-7
6+4*1-5(3-2)=5
