To calculate 70 - 56 on a number line, one can either start at 70 and count backwards 56 places, or start at 56 and count forward until reaching 70, with both methods resulting in the difference of 14.
To find 70 - 56 using a number line, you can use two different methods:
Backward Jump: Start at 70 on the number line and make a backward jump of 56 units. After jumping 56 units back, you land on 14, which is the answer.
Forward Jump: Start at 56 on the number line and determine how many units you need to move forward to reach 70. By counting forward, you find that it takes a jump of 14 units to go from 56 to 70, and thus, 70 - 56 equals 14.
Both methods will visually show you that the difference between 70 and 56 is 14 on a number line.
