When you're faced with math problems involving multiple operations, BIDMAS is your best friend. BIDMAS stands for Brackets, Indices, Division/Multiplication, Addition/Subtraction. Understanding this order helps solve problems systematically.

In BIDMAS, anything in brackets should be tackled first. Then move on to powers or roots, followed by multiplication or division. Finally, proceed with addition and subtraction. In simpler problems like \(-1 + 3 - (-4) + 10\), we don't see brackets or powers, so we move directly to addition and subtraction. Here, you simply work from left to right, since both operations share equal priority.

Having a clear grasp of BIDMAS ensures that you handle more complex equations confidently and accurately.

Addition and subtraction can appear straightforward, but they need careful attention, especially in longer equations. Always move from left to right when dealing just with these two operations, as we did in the example problem.

Each step you take in an equation requires accuracy. Start by adding \(-1\) and \(3\), giving you \(2\). Next, deal with the subtraction, but remember subtracting a negative number is the same as adding the positive counterpart. Finally, perform the last addition step. By breaking it down into small operations, you make it manageable.

Ensure to double-check each step to avoid simple mistakes in longer computations.

Negative numbers can sometimes be confusing, especially if you encounter subtraction involving negatives. The simplest rule to remember is that subtracting a negative number is like adding its positive counterpart. For example, \(2 - (-4)\) becomes \(2 + 4\).

Think about it like a double negative in language which turns into a positive. In our exercise, this was a key step that made the problem straightforward once handled correctly. Always double-check the signs involved in your calculations to ensure accuracy.

Understanding negative numbers and how they interact with addition and subtraction will strengthen your overall math skills and reduce errors.
