Subtraction With and Without borrowing (regrouping) for kids

hello guys in today's lesson we are learning about multiple

subtraction

or

subtraction

with and without

borrowing

in today's video we are learning about multi-digit subtraction a multi-digit number is just a number that has more than one digit, like 32 is a two-digit number that has a two in ones and a strong three or the number 215 is a three-digit number it has a five and the ones have one in tens and a two in hundreds multi-digit subtraction is very similar to addition of several digits with only very few differences So what is the difference between addition and subtraction?

The difference is that in subtraction, when we remove numbers, the order of the numbers we remove matters. With addition, you can switch to numbers and still get the same result. example three plus five equals two is the same as five plus three but we can't say the same for subtraction if you have the problem 9 subtract 4 equals 5 you can't get the same answer if you have 4 subtract 9 In fact, it is You may get confused and think that you can still take the smaller number away from the larger number, but in reality you can't because subtraction doesn't work like that, so with multiple number subtraction it's very important to always remember that.

Order matters, so when we have a problem like this, the first thing we do is what we did for a melody. First you must stack the numbers, but you must make sure that the first number, which is the number that you are taking from is always the largest number and goes on top and the number that you are taking away goes on the bottom, so Let's set these numbers up with the largest number at the top and the places are in a column below each one. others and then so the places are in a column below each other in line and of course you will need the straight line just below them and the minus sign on the left side now to start removing or subtracting, like We always start with the ones column and then we go to the tenths and you always subtract the bottom number from the top, so we start with eight minus five equals three and then four minus three equals one now we can say 48 minus 35 is equal to 13 or we can say that the difference between 48 and 35 is 13.

Now let's try another problem: 134 subtracts 28 and the first thing we always do is stack the numbers so that the largest number is on top and the smallest number is on the bottom. final. below and all the place values ​​are lined up equally so the ones are in a column, the tens are in a column and the hundreds are in a column and we draw a line under the numbers for our answers and also a minus sign on the left. side to show that we are subtracting and as we always do, we start with the ones columns and then we go to the left of the tens and hundreds, so with the four ones column we subtract eight uh-uh and that's when It gets a little complicated four is less than eight so what are we going to do?

Of course, things like this always happen when the number above is less than the number below and in situations like this you need to borrow from the number next to it. for them so here's how to do it: you borrow a one from the tens place, which is a three and that changes the three to one, but the one you borrowed from the three is actually not a one, it's a ten and that changes. number four to fourteen which is ten plus four now we are ready to subtract fourteen minus eight is equal to six two minus two is equal to zero one and we can pretend that there is a zero here minus zero is equal to one so the difference between these two numbers It's one hundred and six and this process that we just did is called loan subtraction, which is a little complicated.

Now let's do another subtraction with loan. 537 subtracts 69, so first we stack the numbers where the ones are in a column. the tens are in a column and the hundreds are in a column, then we draw the line just below them to show the answers and of course we draw a minus sign on the left side to show that we are subtracting and as always we start with the ones the seven is removed, now another complicated situation where the top number is smaller than the bottom number where we have to borrow from our neighbor number three, so we borrow a one from the number three which changes from three to two and then that which is actually a ten is added to seven which makes it seventeen now we can subtract seventeen subtract nine equals eight now we move to the tens places two subtract six another complicated situation where the number above is less that the bottom number where we need to borrow from our neighbor number five, so five becomes four and two becomes twelve.

Now that we've borrowed, we have twelve, we subtract six, which equals six and then where we don't have a zero. here we can imagine that there is zero here we can say four minus zero equals four now you can say that the difference between two numbers is four hundred and sixty-eight so let's try another problem with four legitimate numbers one thousand eight hundred and fifty minus one thousand three hundred and fifty-four first we need set up the numbers where the ones places are in a column the tens places are in a column the hundreds in a column and the thousands in a column then we draw our line below to show our answers and we draw the minus sign to show that we are subtracting so we start with our places zero minus four now the top number is smaller than the bottom number where we need to borrow from our next door neighbor the number five who turns the number five into a four and changes number zero into ten now ten minus four equals six now we move on to our tens place four minus five again the top number is smaller than the bottom number where we need to borrow the number 8 from our next door neighbor which makes the number 8 7 and then that which is actually a 10 converts the number 4 into 14. now in the tens place we have 14 minus five which is equal to nine then to the hundreds seven minus three is equal to four then we move on to the thousands one minus one equals zero so we don't actually need to show that zero so we can say that the difference between 1850 and 1354 is 496.
