Studdy Solution
Calculate the result of the twelfth sum.
.5+14=.25-.5+\frac{1}{4} = -.25The solutions to the sums are10. 7+()=57+(-)=5
13. 11+12=11+12=
16. +()=0+(-)=0
11. 9+9=0-9+9=0
14. +(8)=5+(-8)=-5
17. +(6)=9-+(-6)=-9
19. 75+(25)=100-75+(-25)=-100
20. 100+1=99-100+1=-99
22. (0.75)+(0.25)=1(-0.75)+(-0.25)=-1 . (4)+0.5=.5(-4)+0.5=-.5
5. (4)+(14)=1\left(-\frac{}{4}\right)+\left(-\frac{1}{4}\right)=-1
26. (1)+14=.25\left(- \frac{1}{}\right)+\frac{1}{4}=-.25
