तीन अंकों का घटाव

Video narration

Do you get stuck when the top digit is too small, or when hundreds, tens, and ones land in wrong places? Think of rupees: you have 542 rupees and spend 278. Subtraction finds what remains. In 542, 5 is hundreds-the सैकड़ा place, 4 is tens-the दहाई place, and 2 is ones-the इकाई place. Write 278 underneath, matching places. Start on the right. Two ones cannot pay eight, so borrow one ten. Four tens becomes three, and two ones becomes twelve. Twelve minus eight is four. Three tens cannot pay seven, so borrow one hundred. Five hundreds becomes four, and three tens becomes thirteen. Thirteen minus seven is six. Finally, four minus two is two. The answer is 264 rupees. Check: 264 plus 278 equals 542. Line up the places, start with ones, and borrow when needed. Then subtracting rupees-or any three-digit number-is easy.
