# SSAT Elementary Level Math : How to identify the parts of a list

## Example Questions

Explanation:

### Example Question #71 : Sets

Which of the choices below lists ONLY examples of triangles?

isosceles, scalene, equilateral

pentagon, isosceles, kite

equilateral, parallelogram, trapezoid

rhombus, kite, trapezoid

isosceles, scalene, equilateral

Explanation:

isosceles: triangle with two equal sides and two equal angles

scalene: triangle with no equal sides and no equal angles

equilateral: triangle with three equal sides and three equal angles

### Example Question #2 : How To Identify The Parts Of A List

Define the set

Which of the following is a subset of ?

Explanation:

A subset of a set , by definition, is any set that contains no elements not in .  Each of the following subsets can be seen to have at least one such element, which is underlined here:

The remaining set can be seen to have only elements from :

This is the correct choice.

### Example Question #4 : How To Identify The Parts Of A List

Define two sets as follows:

How many elements are in ?

Explanation:

is the union of sets  and  - the set of all elements that appear in either  or . These elements are:

which is a set with twelve elements.

### Example Question #5 : How To Identify The Parts Of A List

Use the given multiplication to find a pattern, and then solve the following:

Explanation:

### Example Question #3 : How To Identify The Parts Of A List

Place the following numbers in order from smallest to largest:

Explanation:

For negative numbers, the bigger the value next to the negative sign, the smaller the number. For example,  is smaller than

Use the tenths digit (the one to the right of the decimal point) to order the numbers:

The negative numbers with a  in the tenths place are smaller than the numbers with a  in the tenths place.

Then, use the hundredths place to order the numbers:

is smaller than  since  is larger than

is smaller than  since  is larger than

### Example Question #72 : Data Analysis

Which of these numbers is not a prime number?

Explanation:

A prime number has exactly two factors: 1 and itself. 85 is immediately disqualified: any number that ends in 5 has 5 as a factor.

### Example Question #73 : Data Analysis

Place the following numbers in order from least to greatest:

Explanation:

First, use the tenths digit (the one to the right of the decimal point) to order the numbers.

The numbers with a 6 in the tenths place are smaller than the numbers with a 7 in the tenths place.

Then, use the hundredths place to order the numbers.

0.66 is smaller than 0.69 since 6 is smaller than 9.

0.70 is smaller than 0.71 since 0 is smaller than 1.

### Example Question #9 : How To Identify The Parts Of A List

Order these objects from largest to smallest. The vase is  inches, the table is  inches, and the flowers are  inches.

Table, flower, vase

Vase, flower, table

Flower, vase, table

Table, vase, flower

Flower, table, vase

Table, flower, vase

Explanation:

When ordering objects from largest to smallest, you need to compare the numbers. The largest number will always be the largest object. In this case, the number  is bigger than  and  so the table comes first. The number  is bigger than  so the flower comes next. The number  is the smallest number, so the vase is the smallest object.

### Example Question #1 : How To Identify The Parts Of A List

Order these objects from largest to smallest. The sun is  inches, the star is  inches, and the moon is  inches.

Moon, star, sun

Sun, star, moon

Star, sun, moon

Sun, moon, star

Moon, sun, star
