Subtraction using standard algorithm

WebThe basic idea is that the number is broken apart into tens and ones and then, either using a number line, base-10 blocks or just numbers, students manipulate the pieces to add or subtract the numbers. Breaking the number part or ungrouping it helps students see the value of place value. The tens place is not just 4. Its value is 40 or 4 tens. WebFirst thing: Drag the 8 down. Now, let's go back into our division, multiplication, subtraction loop using the 8! Division: We want to see how many times 2 will go into 8 ... 2 goes into 8 four times... So, we put that 4 right above the 8: Multiplication: Multiply the 4 and the 2 and put the answer right under the 8: Subtraction: That's 8 - 8 = 0

WebIn this lesson you will learn how to subtract multi-digit whole numbers by using the standard subtraction algorithm. WebUsing the standard approach, we write: 6354 2978 ——- and work as follows: 1) 8 is greater than 4 so we “borrow 1” from the 5 and then subtract 8 from 14 and get 6. We cross out the 5 and write 4 to account for the borrowing; 2) 7 is greater than 4 so we borrow 1 from the 3 and then subtract 7 from 14 and get 7.
