For example, if you have the numbers 2 and 3, you can find the product by multiplying them together: 2 x 3 = 6. Multiplication is the operation of finding the product of two or more numbers. Subtraction can also be represented using the “-” symbol, for example 7 – 3 = 4. For example, if you have the numbers 7 and 3, you can find the difference by subtracting 3 from 7: 7 – 3 = 4. Subtraction is the operation of finding the difference between two numbers. ![]() Addition can also be represented using the “+” symbol, for example 2 + 3 = 5. For example, if you have the numbers 2, 3, and 4, you can find the total by adding them together: 2 + 3 + 4 = 9. These operations are used to solve problems and understand mathematical concepts.Īddition is the operation of finding the total of two or more numbers. The four basic math operations are addition, subtraction, multiplication, and division. Similarly, if you need to express a fraction as a percentage, you can divide the numerator by the denominator and then multiply by 100 to get the percentage. For example, if you need to find 25% of a number, you can convert 25% to the decimal 0.25 and then multiply it by the number. ![]() It is important to be able to convert between fractions, decimals, and percentages in order to solve problems and understand mathematical concepts. For example, 75% can be written as 75/100. To convert a percentage to a fraction, you can divide the percentage by 100, and write the fraction with a denominator of 100. To convert a percentage to a decimal, you can divide the percentage by 100. Percentages are used to indicate the proportion of a value in relation to 100. Percentages are a way of expressing a number as a fraction of 100, and are represented by the symbol % (e.g. For example, 0.75 can be written as 75/100. To convert a decimal to a fraction, you can write the decimal as a fraction with a denominator of 10,100,1000, etc. Decimals are a convenient way to express values that are not whole numbers, for example, 0.75 represents the value of 3/4. When the numerator and denominator are the same, the fraction is equal to 1, such as 1/1.ĭecimals are a way of expressing fractions with a denominator of 10 or a power of 10, and are represented by a point (e.g. The top number, also known as the numerator, represents the number of parts being considered, while the bottom number, also known as the denominator, represents the total number of parts in the whole. ![]() HESI Basic Math HESI Basic math conceptsįractions, decimals, and percentages are all concepts that are fundamental to basic math.įractions represent a part of a whole, and are represented by two numbers separated by a slash (e.g. By following this guide, you will be well-equipped to succeed on the HESI A2 Math test.
