Question about Casio DR-T220 Calculator
My work book tells me to use the "plus equal" key for certin equations...problem is...there isn't one! im using a casio DR-T220...is there another way to get the same effect as the "plus equal button? and if so...how?
Press the plus key again, it should work. ie put a number in and press the plus key twice, it should double, and again it should double again and so on
