Given the equation:
2 + (3 - 9) ÷ 4 ⋅ 4
Solve the equation.
Solution:
In order to solve the equation, we apply the rules of PEMDAS, which means that we need to start first with the parenthesis, exponent, multiplication, division, addition and lastly subtraction. In our case, we start first by solving the values inside the parenthesis.
= 2 + (3 - 9) ÷ 4 ⋅ 4
= 2 + (-6) ÷ 4 ⋅ 4
= 2 - 6 ÷ 4 ⋅ 4
= 2 - 6 ÷ 16
= 2 - 0.375
= 1.625
Final answer:
= 1.625
