## 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

1. Kara - 100*5+26=526 100(5+26)=3100
500+26=526 100 x 31= 3100

2. 70*4+8=288
280+8=288

70(4+8)=840
70*12=840

3. 78/26*3=9 78/(26*3)=1
3*3=9 78/78=1

4. 50*6+11=311 50(6+11)=3300
300+11=311 50(66)=3300

5. 7(3*5)+(9*13)=223
2(9*5)/(60/6)=9

6. 9*10+21=111
9(10+21)=279

7. 7(3*2+1)+51 = 7(6+1)+51 = 7(7)+51 = 49+51 = 100
7*3*2+1+51 = 21*2+1+51 = 42+1+51 = 43+52 = 94

8. 20*10+60/2=13
20(10+60)/2=700

9. 7*20+4=144
140+4=144

7(20+4)=168
7*24=168

10. 13*13-13=156 13*(13-13)=0

11. Drew-(7*8)-5=51
7(8-5)=21

12. 1+1*3=4 or (1+1)3=6

13. 90*3+2=279
200+79=279

90(3+2)=450
400+50=450

14. 30*7+(12-3)=1890 or (30*7)+12-3=219

1. 15. 40 * 3+2 = 122
100 + 22 = 122

40 (3 +2 ) = 200
100 + 100 = 200

16. 5*10+6=56 or 5(10+6)=80
50+6=56 or 5x16=80

17. 10+4*6=34 or ( 10+4)6=84

18. made a mistake 50*6+11=311 or 50(6+11)=850
300+11=311 50(17)=850

19. 3*4+7=19 or 3*(4+7)=33

20. 8+9*3-2=33 (8+9)*3-2=49
8+27-2=33 17*3-2=49
35-2=33 51-2=49

21. 12/4+8*13-6=101 3+8*13-6 3+104-6 107-6=101
12/(4+8)*13-6=7 12/12*13-6 1*13-6 13-6=7 Garrett

22. 7*10+2=72 or 7(10+2)= 84
70+2=72 or 7x12=84
