24×2-7 According to PEMDAS the multiplying part of the equations goes first:
24×2=48
Then do the subtracting part: 48-7=41
The equation equals... =41
Now solve the options for the answer: D. 2^11= 2×2×2×2×2×2×2×2×2×2×2=2048<----not the answer C. 2^3=2×2×2=8<----- not the answer B. 1/2^3=1×1×1=3==3/8<----not the answer 2×2×2=8
Which makes the answer A because all of the other equations are solved!
