Question

2 plus 4 times negative 6 minus 3 times 5

Answer 1

The given expression is:

`2+4(-6)-3(5)`

Recall the acronym for the order of operations, PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.

Follow this order to evaluate the given expression.

Notice that the operations involved here are, Multiplication, Addition, and Subtraction (listed as in the order of operations).

So start with multiplication:

`\begin{gathered} 2+4(-6)-3(5)=2+(-24)-15 \\ \end{gathered}`

Since the positive sign when multiplied by a negative sign gives a negative sign, it follows that the expression simplifies to:

`2-24-15`

Subtract the numbers:

`2-24-15=2-9=-7`

Hence, the value of the given expression is -7.
