For example, if your answer is $1234 you should write 1234 as your answer and if your answer is 4%, write 4 as your answer. b. Indicate a negative number by putting a minus sign in front. Therbfore, if your answer is negative 1234 you need to post -1234 as your answer. c. Round your answer to the nearest whole number, I.e. no decimal points.
