# PSAT Math : How to add integers

## Example Questions

### Example Question #1 : How To Add Integers

My sister invited me to play an online word game. In the game vowels (a,e,i,o,u) are worth 3 points and consonants are worth 5. How much would I score if I use the word “University” ?

45

30

42

63

42

Explanation:

In the word we have 4 vowels (3 x 4 = 12 points) and 6 consonants (5 x 6= 30). If we add the points together we get a total of 42 points.

### Example Question #1 : How To Add Integers

What is the sum of multiples of 10 from 10 to 140 inclusive?

1100
1000
1050
950
900
Explanation:

Listing them all, 10-20-30-40-50-60-70-80-90-100-110-120-130-140 you see you can divide the numbers in half (7 pairs). Alternatively you can take (140-10+10)/2/10, adding that additional +10 in the numerator because it is inclusive, giving you 7. Just adding the top and bottom numbers gives you 10+140 for 150. 150*7 is 1050.

### Example Question #1 : How To Add Integers

What number replaces the circle in the following sequence?

Explanation:

The sequence is formed by starting with 1 and adding successive powers of 5. The numbers are obtained as follows:

- the correct response.

### Example Question #11 : Basic Operations

Suppose you know the values of the variables in the expression

and you wish to evaluate it.

Which operation do you execute last?

Squaring

Multiplication

Division

Subtraction

Explanation:

In the absence of grouping symbols, the first operations that should  be carried out are exponentiations, followed by multiplications and divisions, followed by additions and subtractions.

The additions and subtractions are carried out from left to right. Since the addition is the one to the right, it is performed last.
