ok just add or subract the number you have as if there was no decimals. once you do that and get your answer move your points 3 times. you move it three times because the decimal that has the most numbers after a point is the last one and it has 3 numbers after the point so move your point 3 times... Your answer should be "4.243"

Hope this helped
