The best thing that would first be done in the aspect would be to first sum up the numbers that are in parenthesis.

Let's keep in mind that a (-)+(-) would equal a positive. This would mean that a negative number, plus another negative number would then be a positive number.

Your answer: <span>1.14200 </span>

During his hike, Milt drank 1 liter of water and 1 liter of sports drink. How many milliliters of liquid did he drink?
S_A_V [24]

Answer: 2,000 milliliters.  

Step-by-step explanation:

Hi, to answer this question we have to add the amount of water and the amount of sports drink that he drank:

1 liter + 1 liter = 2 liters of liquid.

Finally, we have to convert the result into milliliters.

Since 1 liter = 1000 liters

We have to multiply the liters drank by 1000.

2 x 1000 = 2,000 milliliters.  

Feel free to ask for more if needed or if you did not understand something.
