6. How to avoid slipping on rainy days

When it rains, the ground becomes more slippery and we can easily fall if we are not careful.

It is also good to wear shoes with non-slip soles and avoid stepping on puddles or smooth surfaces.

7. How to make a homemade compress

8. How to multiply large numbers mentally

If you want to do quick calculations without using a calculator, there are some tricks you can use to multiply large numbers in your head. For example, if you want to multiply 25 by 16, you can do it like this: 25 x 16 = (25 x 10) + (25 x 6) = 250 + 150 = 400. Another way is to round the numbers to the nearest ten and then adjust the result. For example: 25 x 16 = (30 x 15) - (5 x 15) - (5 x 1) = 450 - 75 - 5 = 370.

Finally, cover the wound with a sterile bandage or dressing and change it every day until it heals.
