Advice

You need to check in which order your calculator carries out the operations.

If, when you input $2+3 \times 4$ you get the answer $14$ , then your calculator is scientific and will perform multiplication and division before addition and subtraction. If you get the answer $20$ then your calculator is performing operations in the order written.

Be careful with negative numbers. Remember that squaring a negative number gives a positive number. For instance if you are using your calculator to find the square of $-6$ you need to input $(-6)^2$ , not $-6^2$ .

Give a worked solution to the whole question.
