Question

0.019 + (2.3 * 10-4)

Answer 1

19.019

Explanation:

Follow the order of BIMDAS

1. you do what's inside the brackets, so let's forget the 0.019 for now

0.019 + (2.3*10 - 4)

2. multiplication/division goes before addition/subtraction, hence you multiply 2.3 by 10 first

0.019 + (23 - 4)

3. Since 23 and -4 are still in the brackets, so we do that first

0.019 + 19

4. Add from left to right

= 19.019

Answer 2

19.019

Explanation:

Let's solve this problem using the order of operations, or PEMDAS.

0.019 + (2.3 × 10 - 4) = 0.019 + (23 - 4) = 0.019 + 19 = 19.019

Hope this helps!
