Example Question #111 : Integer Operations
When evaluating the expression
which of the five operations must be carried out third?
Division
Addition
Multplication
Squaring
Subtraction
Multplication
In the order of operations, in the absence of grouping symbols, the first operation to be carried out must be the exponent (squaring). The next operations must be the multiplication and division, in left-to-right order. The division is at left, so the dvision must be carried out second, and the multiplication third. This makes multiplication the correct choice.
Example Question #116 : Integer Operations
Multiply the two numbers:
Multiply the two and eight.
The tens digit, 
Multiply the six and eight and add the carryover.
Combine the numbers.
The answer is:
Example Question #117 : Integer Operations
Multiply:
