At the grocery store, you buy a carton of milk for $1.25, a loaf of bread on sale for $0.35, and a box of cereal for $3.75. use mental math to find the total cost of the groceries.

Here, We have to do the addition. We know, addition is quite simple but our main motive is "My Mental" (without any use of pencil & paper)

So, Your inputs are: 1.25 + 0.35 + 3.75

Now, we know, 0.25 + 0.75 = 1.00 so we will add 1.25 & 3.75 first which would be equal to 5.00 and 0.35 would make 5.35

In short, Your Answer would be: $5.35

Hope this helps!

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's.
