Solve the subtraction exercise using jumps on the number line below:
To solve the subtraction using a number line, we follow these steps:
By effectively using the jumps on a number line, we deduce that .
Thus, the solution to the subtraction exercise is .
If we have 67 blocks in total, how many blocks will remain if we remove 5 tens and 4 ones?
Breaking numbers apart makes mental math easier! It's much simpler to subtract nice round numbers like 60 first, then handle the remaining 7. This prevents counting errors on long jumps.
That works too! You could jump back 50 to get 46, then back 17 more to reach 29. The decomposition method doesn't matter as long as the parts add up to 67.
For subtraction, always jump backward (to the left). Think of it as 'taking away' - you're moving to smaller numbers. Addition jumps forward (right) to bigger numbers.
Yes! Number line jumping works for any subtraction. For larger numbers, break them into hundreds, tens, and ones. For smaller ones, you might jump the whole amount at once.
If your starting number is smaller than what you're subtracting, you'll land below zero. That's okay - it means your answer is negative! Just keep counting backward from zero.
