Solve '20-0÷4×3+1': Order of Operations Practice

Let's simplify this expression while following the order of operations which states that exponents come before multiplication and division, which come before addition and subtraction, and that parentheses come before all of them,

According to the above order of operations, multiplication and division come before addition and subtraction, so we'll start by calculating the value of the second term from the left in the expression, then we'll perform the addition and subtraction operations, since between multiplication and division operations there is no precedence according to the above order of operations, we'll perform the division and multiplication operations in the second term from the left one after the other from left to right (which is the natural order of operations):

$20-0:4\cdot3+1= \\ 20-0\cdot3+1=\\ 20-0+1=\\ 21$

In the first stage, we remembered that dividing 0 by any number (other than zero) will always yield the result 0, then we remembered that multiplying 0 by any number will always yield the result 0,

Therefore, the correct answer is answer B.
