Example Question #41 : Operations
Evaluate
When doing multiple operations, always remember PEMDAS. There is division and addition. D comes first and is the division so we do that first followed by addition. So we have 
Example Question #42 : Operations
Evaluate
When doing multiple operations, always remember PEMDAS. There is division and multiplication but parantheses present. P is parantheses and always has priority over every operation. So let's work the math inside the parantheses. So we have 
Example Question #43 : Operations
Evaluate
When doing multiple operations, always remember PEMDAS. There is division and subtraction. D is division and has priority over subtraction. So we have 
Example Question #44 : Operations
Evaluate
When doing multiple operations, always remember PEMDAS. There is exponents and subtraction. E is exponents and has priority over subtraction. So we have 
Example Question #45 : Operations
Evaluate
When doing multiple operations, always remember PEMDAS. There is parentheses, exponents, multiplication, addition, and subtraction. We will work the parentheses first, follow by exponent thenaddition, then multiplication, and finally subtraction. So we have 
Example Question #46 : Operations
Evaluate
When doing multiple operations, always remember PEMDAS. There are parantheses, exponents, multiplication, addition and subtraction. We will do the parantheses first, then exponents, then multiplication, addition and last subtraction. So we have 
Example Question #47 : Operations
Evaluate.
When doing multiple operations, always remember PEMDAS. There is addition and subtraction and they are grouped together as last priority. So we just do the operations from left to right.
Example Question #48 : Operations
Evaluate
When doing multiple operations, always remember PEMDAS. There is division and multiplication. They are grouped together is third priority. So must work from left to right.
The answer is 
Example Question #49 : Operations
Evaluate
When doing multiple operations, always remember PEMDAS. There is addition and multiplication but parantheses present. There is multiplication because the 
Example Question #50 : Operations
Evaluate
When doing multiple operations, always remember PEMDAS. We have parenthesis, exponents, multplication, and division. We will do the parenthesis first followed by exponents and multiply and divide from left to right. So we have
