Solving Equations


Equation 1: (5)-(-7)=?


When solving equations, it is important to remember the order of operations (PEMDAS) which stands for:



  • Parentheses

  • Exponents

  • Multiplication and Division (from left to right)

  • Addition and Subtraction (from left to right)



In this particular equation, we have subtraction and a negative sign, so we need to simplify the expression by following the order of operations:



  1. The negative sign in the parentheses means that we need to change the sign of the number inside the parentheses, which gives us: (5) + 7

  2. Adding 5 and 7 gives us the final answer of: 12



Equation 2: (1)(-2)=?


In this equation, we have multiplication and a negative sign, so we need to simplify the expression by following the order of operations:



  1. Multiplying 1 and -2 gives us the expression: -2



Therefore, the final answer for this equation is: -2
