1. What is two-digit addition and subtraction?
Two-digit addition and subtraction are mathematical operations that involve adding or subtracting numbers that have two digits. For example, adding 34 and 56 or subtracting 78 from 92.
2. How do I perform two-digit addition?
To perform two-digit addition, align the numbers vertically with the ones digit in the same column. Add the ones digit first and then move on to the tens digit. If the sum of the ones digit is greater than 9, carry over the tens digit to the next column.
3. Can you provide an example of two-digit addition?
Of course! Let’s add 45 and 67:
45
+ 67
—-
112
4. How do I perform two-digit subtraction?
To perform two-digit subtraction, align the numbers vertically with the ones digit in the same column. Subtract the ones digit first and then move on to the tens digit. If the difference of the ones digit is negative, borrow from the tens digit in the next column.
5. Can you provide an example of two-digit subtraction?
Sure! Let’s subtract 78 from 92:
92
– 78
