explain how you can find the sum 25 + 59 without paper, pencil or calculator. Find the sum? How do I do this
You could add 20 and 60 = 80.
And add 4 more.
Or -- you could add 25 and 60 and subtract 1.
Do 20+50 which is 70 then 5+9 which is 11 then add 70+11.
To find the sum of 25 + 59 without using any tools such as paper, pencil, or calculator, you can use mental math. Here's how you can do it:
1. Start by adding the ones place digits: 5 + 9 = 14.
2. Since 14 is greater than 10, you need to carry the tens place value to the next column.
3. Add the tens place digits along with the carried value: 1 (carried) + 2 + 5 = 8.
4. Write down the resulting digits together, starting with the ones place and then the tens place: 84.
Therefore, the sum of 25 + 59 is 84.
