Final answer:
The answer to 2 + 5 * 4 - 8 following the BIDMAS/PEDMAS rule (Brackets, Indices, Division and Multiplication, addition and subtraction) is 14.
Step-by-step explanation:
The expression you are asking for help with is an arithmetic problem. The order in which different operations are performed can be remembered using an acronym, BIDMAS or PEDMAS, which stands for Brackets/parentheses, Indices/Exponents, Division and Multiplication (left-to-right), addition and subtraction (left-to-right).
In your case, we have 2 + 5 * 4 - 8. The multiplication should be carried out before the addition and subtraction because of the BIDMAS/PEDMAS rule. Solve it as follows:
- 5 * 4 = 20,
- thus, the expression becomes 2 + 20 - 8,
- adding 2 + 20 = 22,
- and subtracting 22 - 8 gives 14 as the final answer.
