Here we will show you step by step how to calculate 102 minus 45 using the long subtraction method. We will first give you step-by-step instructions, and then we will show you an image to illustrate what we did.
Before we continue, note that 102 is the minuend in this problem, and 45 is the subtrahend. To solve the problem 102 minus 45 using long subtraction, we write the minuend on top and the subtrahend below it. Make sure to align the numbers by place value.
Starting from the rightmost column, subtract each subtrahend digit from the corresponding digit of the minuend. If the minuend digit is smaller than the subtrahend digit, borrow 1 from the column to the left and add 10 to the minuend. Continue subtracting from right to left, borrowing as needed.
As promised, below is an illustration showing you how to calculate 102 minus 45 (102 - 45) using the long subtraction method described above.
