To solve the problem [tex]\( 70 + 55 \)[/tex], follow these steps:
1. Identify the two numbers to be added:
- The first number is [tex]\( 70 \)[/tex].
- The second number is [tex]\( 55 \)[/tex].
2. Start by adding the units (ones) digits:
- The units digit of [tex]\( 70 \)[/tex] is [tex]\( 0 \)[/tex].
- The units digit of [tex]\( 55 \)[/tex] is [tex]\( 5 \)[/tex].
- Adding these together: [tex]\( 0 + 5 = 5 \)[/tex].
3. Then add the tens digits:
- The tens digit of [tex]\( 70 \)[/tex] is [tex]\( 7 \)[/tex].
- The tens digit of [tex]\( 55 \)[/tex] is [tex]\( 5 \)[/tex].
- Adding these together: [tex]\( 7 + 5 = 12 \)[/tex].
- Since [tex]\( 12 \)[/tex] is a two-digit number, the result has [tex]\( 2 \)[/tex] in the tens place and [tex]\( 1 \)[/tex] in the hundreds place.
4. Combine both results:
- The units place already has [tex]\( 5 \)[/tex].
- From the tens place addition, write [tex]\( 2 \)[/tex] in the tens place.
- Include the [tex]\( 1 \)[/tex] from the sum of the tens place (carrying over from tens to hundreds).
5. Combine all the parts:
- Therefore, the total sum is [tex]\( 125 \)[/tex].
Hence, the answer to [tex]\( 70 + 55 \)[/tex] is [tex]\( 125 \)[/tex].
