Subtraction Made Simple: Learn with Fun Animations

Let's learn about subtraction with Spark.E!Subtraction is when we take away some things from a group.Here we have eight apples. If we take away three apples......we are left with five apples.The minus sign tells us we're taking something away.When we subtract numbers, the answer we get is called the difference.Let's try another example with six blocks.If we take away two blocks......we are left with four blocks.Now it's your turn! Here are seven stars.If we take away four stars...We are left with three stars!To make subtraction easier, we can break larger numbers into tens and ones.Let's look at the number 45. It has 4 tens and 5 ones.We can write 45 as 40 plus 5.Similarly, 23 is 20 plus 3.Now we can subtract the tens: 40 minus 20 equals 20.Then subtract the ones: 5 minus 3 equals 2.Finally, we add our results: 20 plus 2 equals 22.Let's try another example: 67 minus 32.Again, we break down 67 into 60 plus 7, and 32 into 30 plus 2.First subtract the tens: 60 minus 30 equals 30. Then the ones: 7 minus 2 equals 5.Adding our results gives us 35.Now we'll learn about borrowing in subtraction when the top digit is smaller than the bottom digit.In this problem, thirty-two minus fifteen, we can't subtract five from two in the ones place.When we try to subtract five from two, we run into a problem because two is smaller than five.To solve this, we borrow one ten from the tens place. When we borrow one ten, it becomes ten ones.The 3 in the tens place becomes 2, and the 2 in the ones place becomes 12.Now we can subtract! Twelve minus five equals seven in the ones place.And two minus one equals one in the tens place.Let's review what we learned about borrowing in subtraction.Now you know how to borrow when subtracting larger numbers!
