Perform all additions and subtractions working from left to right. Leave the parentheses 4 - 3 4 - 6 3 Do the operation in the brackets 4 - 3 -2 3 The bracket informs you to multiply the number within which is -3 x -2 4 6 3. The first thing to evaluate there is the exponent 6 2.
Continue working inside the parentheses by evaluating the division 36 9.
The parentheses group 3 and 2 together and 6 and 4 together and the square brackets tell us to do all the calculations inside them before multiplying by 4. The parentheses group 3 and 2 together and 6 and 4 together and the square brackets tell us to do all the calculations inside them before multiplying by 4. For nested parentheses or brackets solve the innermost parentheses or bracket expressions first and work toward the outermost parentheses. This video provides an example of how to solve a linear equation in one variable.
