Hi I am not good with math. Please tell me how to differentiate mixed numbers, order of operation,subtraction, divide and multiplication etc.
Thanks!
Hi there! I'd be happy to explain how to differentiate mixed numbers and the basic operations of math.
1. Differentiating Mixed Numbers:
To differentiate a mixed number, you need to separate the whole number part from the fractional part. For example, let's say you have the mixed number 3 1/2. To differentiate it, you would treat the whole number part (3) as a separate number and the fractional part (1/2) as another separate number.
2. Order of Operations:
The order of operations is a set of rules that tell you which operation to perform first when you have multiple operations in a single expression. The most commonly used order of operations is called PEMDAS, which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. Here's a breakdown:
- Parentheses: Perform any calculations inside parentheses first.
- Exponents: Evaluate any exponentiation (raising a number to a power) next.
- Multiplication and Division: Perform multiplication and division from left to right.
- Addition and Subtraction: Perform addition and subtraction from left to right.
For example, in the expression 4 + 2 x 3, you would perform the multiplication first (2 x 3 = 6) and then the addition (4 + 6 = 10).
3. Subtraction:
Subtraction is one of the four basic operations in math. To subtract one number from another, you need to find the difference between the two numbers. If you're subtracting whole numbers, you can align them vertically and subtract each place value column from right to left. If you're subtracting mixed numbers, you first need to convert them to improper fractions, and then you can subtract them by subtracting the numerators and keeping the common denominator.
4. Division:
Division is another basic operation in math. To divide one number by another, you need to find out how many times the divisor (the number you're dividing by) can fit into the dividend (the number you're dividing). You can perform division using long division or by using a calculator.
5. Multiplication:
Multiplication is the process of adding a number to itself a certain number of times. To multiply two numbers, you can use the multiplication sign (*) or simply write the numbers side by side. For example, 3 * 4 = 12, or 3(4) = 12.
I hope this helps! Let me know if you have any more questions.
