To substract the numbers shown by the method known as the "Arrow way" you must rewrite 430 and substract the hundredths (In this case, it is 200). Then you have to substract the tenths to that result (Result obtained-30). This explanation is shown below:
430 --( -200 )---> 230 --( -30 )---> 200
Therefore,the solution of the mathematical operation 430-230, using the arrow way, is: 200
form of devision that takes longer bc it a fraction or decimal. first you want to get rid of the decimals. then devide the numbers from the lowest to the highest
I may be wrong been for ever since I did it on paper
