The first topic that we will discuss is whole numbers. Whole numbers are numbers that do not have fractions or decimals, such as 0, 1, 2, 3, and so on. In this topic, you will learn how to perform various operations with whole numbers, such as addition, subtraction, multiplication, division, and mixed operations. You will also learn how to compare and order whole numbers using symbols such as (greater than), = (equal to), (less than or equal to), (greater than or equal to), and (not equal to).

Here are some examples of math problems on whole numbers that you can find in the link above:
What is the result of the operation 5 x 3 + 2 x 4 - 6 2 = ?
A) 20
B) 21
C) 22
D) 23
The correct answer is B) 21. To solve this problem, you need to follow the order of operations, which is parentheses, exponents, multiplication, division, addition, and subtraction. You can remember this order by using the acronym PEMDAS or the phrase Please Excuse My Dear Aunt Sally. In this problem, there are no parentheses or exponents, so you can start with multiplication and division. You can do them from left to right, as they have the same priority. So, you can do:
5 x 3 + 2 x 4 - 6 2 =

15 + 8 - 3 =
Then, you can do addition and subtraction from left to right, as they have the same priority. So, you can do:
15 + 8 - 3 =
23 - 3 =
20
Which of the following statements is true?
A) 7
B) 9 > 10
C) 6 = 6
D) 8 8
The correct answer is C) 6 = 6. To compare two whole numbers, you need to look at their values and use the appropriate symbols. The symbol means greater than, which means that the number on the left is larger than the number on the right. The symbol = means equal to, which means that the number on the left has the same value as the number on the right. The symbol means not equal to, which means that the number on the left has a different value from the number on the right. In this problem, only statement C) is true, as 6 has the same value as 6.

The second topic that we will discuss is powers and roots of whole numbers. Powers and roots are ways of expressing repeated multiplication or division of a number by itself. For example, 2 means 2 x 2 x 2, which is equal to 8. This is called a power or an exponent. The base is the number that is multiplied by itself, which is 2 in this case. The exponent is the number that shows how many times the base is multiplied by itself, which is 3 in this case. On the other hand, 16 means what number multiplied by itself equals to 16. This is called a root or a radical. The radicand is the number under the root sign, which is 16 in this case. The index is the number that shows what kind of root it is, such as square root (), cube root (), or fourth root (). If there is no index, it is assumed to be a square root. In this case, 16 = 4, because 4 x 4 = 16.

What is the value of 3 x 2 = ?
A) 9
B) 18
C) 36
D) 72
The correct answer is D) 72. To solve this problem, you need to apply the rule of exponents that says that when you multiply two powers with the same base, you can add their exponents. For example, 2 x 2 = 2 = 2. However, in this problem, the bases are different, so you cannot use this rule. Instead, you need to calculate the value of each power separately and then multiply them. For example, 3 = 3 x 3 = 9 and 2 = 2 x 2 x 2 = 8. Then, you can do:
3 x 2 =
9 x 8 =
72
What is the value of 64?
A) 4
B) 6
C) 8
D) 10
The correct answer is C) 8. To solve this problem, you need to find a number that multiplied by itself equals to 64. This is called a square root, and it is denoted by the symbol . You can use trial and error to find the square root of a number, or you can use a calculator or a table of squares and square roots. In this case, you can see that:
(-8) x (-8) = 64
(8) x (8) = 64
Therefore, 64 = -8 or 64 = 8. However, since we are dealing with whole numbers, we only consider the positive value of the square root, which is 8.

The third topic that we will discuss is measurements of time, angles, distances, and speeds. Measurements are ways of expressing how much or how many of something there is using units such as seconds, minutes, hours, degrees, meters, kilometers, meters per second, kilometers per hour, and so on. In this topic, you will learn how to convert between different units of measurement using ratios and proportions. You will also learn how to use formulas to calculate the time, angle, distance, or speed of an object given some information.

Here are some examples of math problems on measurements of time, angles, distances, and speeds that you can find in the link above:
If a car travels at a constant speed of 10 cm and a width of 5 cm?
Solution:
- Read the problem carefully and identify what is given and what is asked. The problem gives us the length and the width of a rectangle and asks us the area of the rectangle.
- Choose a strategy that suits the problem. In this case, we can use a formula that relates the area, the length, and the width of a rectangle. We know that the area of a rectangle equals to the length times the width, so we can write: Area = Length x Width.
- Show your work and explain your steps. We can plug in the values of the length and the width into the formula and simplify. For example:
Area = Length x Width
Area = 10 cm x 5 cm
Area = 50 cm
- Check your answer and review your solution. Our answer makes sense and satisfies the condition of the problem. We can also check our answer by dividing the area by the length or the width and see if we get the other dimension: 50 cm / 10 cm = 5 cm and 50 cm / 5 cm = 10 cm.
