Question

Evaluate the expression: $24÷(-4)+(-2)·(-5)$

Answer 1

Hint: PEMDAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents(degree or square roots) and later we do operations on multiplication & division and at last addition and subtraction

Step 1: $=24÷(-4)+(-2)·(-5)$

Using PEMDAS rule, division should be performed first

Step 2: $=-6+(-2)·(-5)$

Now, multiplication should be performed

Step 3: $=-6+10$

Now at last addition should be performed

$=+4$

Hence the expression is $+4$.
