0 Paula, I had trouble with this as well. However, I found the solution after playing with the Casio hr -150tm for a while. The reason it will not subtract is because the first number wants to know whether or not it is positive or negative. So, input your first number and press the (+=) button to tell the calculator that the number is positive. Next input your second number and hit the (-) button to subtract. From here on out you can subtract from that number until you clear it. Hope that helps!
