Now, let's work through each step:
Step 1: The problem tells us that .
Step 2: Substitute into the equation where appears: .
Step 3: Calculate the result of the subtraction:
Start from 24 and count backward by 8 units:
Therefore, the solution to the problem is .
If we have 85 blocks in total, how many blocks will remain if we remove 4 tens and 1 one?
The problem specifically tells you that . In math, symbols have exact values - never guess! Always use the given information.
The same rule applies! Look for where the problem tells you the symbol's value. For example, if , then substitute 5 wherever you see the triangle.
Try breaking it down: Start at 24, subtract 4 to get 20, then subtract another 4 to get 16. Or use counting backwards on a number line!
Yes! Symbols can represent any number - whole numbers, fractions, or decimals. Always check what value the problem gives you for each symbol.
This is very common! Always double-check your first step - did you replace every symbol with its number? If you skip substitution, you can't solve the problem correctly.
