Given the numerical equation:
7 + ( 30 - 2 ) = 7 * 23
Evaluate the numerical equation.
Solution:
In order to solve the given numerical equation, we simply need to apply the rules of PEMDAS, which means to start first with parenthesis, exponent, multiplication, division, addition, and subtraction.
7 + ( 30 - 2 ) = 7 * 23
7 + (28) = 161
35 = 161
Transpose 35 on the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
= 161 - 35
= 126
Final answer:
= 126
