The sign you are missing will determine the completion of the equation. To figure this out, we need to determine what sign will make 730 and 10 equal 7300. What about addition? 730+10 = 740. Incorrect answer, addition is not applicable. How about subtraction? 730-10=720. Still incorrect, subtraction is not applicable. What about multiplication? 730 x 10 = 7300. Yes! Multiplication is the correct sign! I hope this helps!
