Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

1. Subtract 13 from 4: 4 - 13 = -9

2. Subtract 5 from -9: -9 - 5 = -14

3. Add 8 to -14: -14 + 8 = -6

4. Add 4 to -6 (since -(-4) = 4): -6 + 4 = -2

5. Divide 15 by 3: 15 ÷ 3 = 5

6. Subtract 5 from -2: -2 - 5 = -7

So, the final answer is: -7

Explanation

The prime numbers less than 25 are: 2, 3, 5, 7, 11, 13, 17, 19, and 23.

Let's add them up:

2 + 3 = 5

5 + 5 = 10

10 + 7 = 17

17 + 11 = 28

28 + 13 = 41

41 + 17 = 58

58 + 19 = 77

77 + 23 = 100

So, the sum of prime numbers less than 25 is: 100

Explanation

When rounding to 2 decimal places, check the third decimal place.

The second decimal place remains unchanged since the third decimal is 0 (less than 5).

Therefore, 6.260 rounds to 6.26.

Explanation

To convert 0.067 into a fraction, write it as $frac{67}{1000}$because there are three decimal places.

The number 67 is in the thousandth place.
