In mathematics, expressions are a combination of numbers, variables, and operators that can be evaluated to obtain a value. The order of operations is a set of rules that dictate the order in which operations should be performed when evaluating an expression. The acronym PEMDAS is often used to remember the order of operations, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
What is 5+3-2+10×2-10 =? Explain
In this case, we have an expression that involves addition, subtraction, and multiplication. By following the order of operations, we can evaluate the expression and obtain the final result.
In this expression, we have a combination of addition, subtraction, and multiplication operations. To evaluate this expression, we need to follow the order of operations, which is a set of rules that dictate the order in which operations should be performed.

The order of operations is as follows:
- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Since we don’t have any parentheses or exponents in this expression, we can start with the multiplication and division.
We have one multiplication operation: 10×2, which equals 20.
Next, we can proceed with the addition and subtraction, starting from the left.
5+3 = 8
8-2 = 6
6+20 = 26
Finally, we subtract 10 from 26, which gives us the final answer:
5+3-2+10×2-10 = 26
Therefore, the value of the expression is 26.
5+3-2+10×2-10 =? – Full Detail
Sure, I’d be happy to provide a more detailed explanation of how to evaluate the expression 5+3-2+10×2-10.
To start, we need to follow the order of operations, which is a set of rules that dictate the order in which operations should be performed. The order of operations is as follows:
- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Since we don’t have any parentheses or exponents in this expression, we can start with the multiplication and division.
We have one multiplication operation: 10×2, which equals 20.
Next, we can proceed with the addition and subtraction, starting from the left.
5+3 = 8
8-2 = 6
6+20 = 26
Finally, we subtract 10 from 26, which gives us the final answer:
5+3-2+10×2-10 = 26
Therefore, the value of the expression is 26.
In summary, to evaluate this expression, we followed the order of operations, which helped us determine the correct order in which to perform the operations. We started with the multiplication, then proceeded with the addition and subtraction from left to right. By following these steps, we were able to obtain the final answer of 26.
