To simplify the given expression, we follow the order of operations (also known as PEMDAS/BODMAS) which states that we first perform any calculations inside parentheses, then any exponents, then any multiplication or division from left to right, and finally any addition or subtraction from left to right.
The expression given is: 18 - 2 * 3 + 622.
First, we perform the multiplication: 2 * 3 = 6.
Now the expression becomes: 18 - 6 + 622.
Next, we perform the subtraction: 18 - 6 = 12.
The expression further simplifies to: 12 + 622.
Finally, we perform the addition: 12 + 622 = 634.
Therefore, the simplified form of the expression 18 - 2 * 3 + 622 is 634.
Simplify: 18−2⋅3+622 .
