• 1.

### A sum is_____________________________________________________

• A.

The difference of two numbers.

• B.

The total amount of two or more addends.

• C.

The greater number.

• D.

The smaller number

• E.

None of the above

B. The total amount of two or more addends.
Explanation
The correct answer is "The total amount of two or more addends." This means that a sum refers to the result obtained when two or more numbers are added together. It represents the total or the combined value of the addends.

### A difference is ____________________________________________

• A.

• B.

Found by comparing numbers or subtracting.

• C.

Found by multiplying.

• D.

Found by dividing.

• E.

Found using the lattice method.

B. Found by comparing numbers or subtracting.
Explanation
The correct answer is "found by comparing numbers or subtracting." This is because when we compare numbers, we can determine which one is larger or smaller. Additionally, when we subtract one number from another, we can find the difference between them.

### A  product is ______________________________________________

• A.

The result when two numbers are multiplied.

• B.

The result when two numbers are divided.

• C.

The result when two numbers are added.

• D.

The result when two numbers are subtracted.

• E.

The result when two numbers are compared.

A. The result when two numbers are multiplied.
Explanation
A product is the result when two numbers are multiplied. Multiplication is an arithmetic operation that combines two numbers to find their total value when they are multiplied together. The product represents the total value or quantity obtained from multiplying the two numbers.

### Parallel lines are always ____________________________________

• A.

Crossing each other.

• B.

Squiggly.

• C.

Part of a square.

• D.

The same distance apart.

• E.

Intersecting.

D. The same distance apart.
Explanation
Parallel lines are always the same distance apart. This is because parallel lines never meet or intersect each other. They maintain a constant distance between them, no matter how far they extend. This property of parallel lines is a fundamental concept in geometry and is used in various applications such as in construction, engineering, and navigation.

A standard unit for measuring temperature.

• C.

A kind of cake.

• D.

Non-standard unit for measuring length.

• E.

Standard unit for measuring weight.

E. Standard unit for measuring weight.
Explanation
A pound is a standard unit for measuring weight. It is commonly used to measure the mass or heaviness of an object. The pound is part of the Imperial system of measurement, primarily used in the United States and a few other countries. It is equivalent to 16 ounces and is often abbreviated as "lb".

• B.

Polygon with 5 sides.

• C.

Circle

• D.

Star with 5 points.

• E.

Square.

### A right angle is always exactly_________________________

• A.

100 degrees

• B.

90 degrees

• C.

45 degrees

• D.

10 degrees

• E.

None of the above

B. 90 degrees
Explanation
A right angle is always exactly 90 degrees. This is a fundamental concept in geometry where a right angle is formed when two lines or line segments intersect each other at a 90-degree angle. It is a fixed measure and does not change. Other options such as 100 degrees, 45 degrees, and 10 degrees do not accurately represent a right angle.

Rate this question:

• 8.

### An obtuse angle is always __________________________

• A.

Less than 90 degrees.

• B.

More than 90 degrees.

• C.

90 degrees.

• D.

There is no such thing as an obtuse angle.

B. More than 90 degrees.
Explanation
An obtuse angle is always more than 90 degrees because an obtuse angle is defined as an angle that is greater than 90 degrees but less than 180 degrees. It is larger than a right angle (90 degrees) but smaller than a straight angle (180 degrees).

Rate this question:

• 9.

### An angle is __________________________________

• A.

Two lines meeting at a common point.

• B.

Intersecting lines.

• C.

Lines that are the same distance apart.

• D.

A closed figure.

A. Two lines meeting at a common point.
Explanation
The correct answer is "two lines meeting at a common point." This is because an angle is formed when two lines intersect or meet at a single point. The point of intersection is called the vertex of the angle. The two lines that form the angle are called the sides of the angle.

Rate this question:

• 10.

### Acute angles are always ________________________

• A.

More than 180 degrees.

• B.

More than 90 degrees.

• C.

Less than 90 degrees.

• D.

Cute angles.

C. Less than 90 degrees.
Explanation
Acute angles are always less than 90 degrees because an acute angle is defined as an angle that measures less than a right angle (90 degrees). Therefore, by definition, any angle that is considered acute will always be less than 90 degrees.

### An algorithm  is __________________________

• A.

A kind of insect.

• B.

A very famous writer.

• C.

A word problem.

• D.

A step by step math plan to find an answer to a problem.

D. A step by step math plan to find an answer to a problem.
Explanation
An algorithm is a step-by-step math plan to find an answer to a problem. It is a set of instructions or a procedure that helps solve a specific problem or complete a task. Algorithms are commonly used in computer science and mathematics to solve complex problems efficiently. They provide a systematic approach and can be implemented using various programming languages.

### Probability  is ________________________________

• A.

The chance that a particular outcome will occur.

• B.

The ability to say yes.

• C.

When things happen the way you want them to.

A. The chance that a particular outcome will occur.
