1. The problem is to calculate $7\tfrac{1}{2} - 20\%$. 2. Convert $7\tfrac{1}{2}$ to an improper fraction or decimal. $7\tfrac{1}{2} = 7 + \frac{1}{2} = 7.5$.

1. **State the problem:** We need to find the value of $5 + 10 \div 2$. 2. **Recall the order of operations:** Division comes before addition.

1. Let's consider the number 4.000. 2. When you round a number, you typically look at the decimal part to decide if you round up or down.

1. Stated problem: Calculate the value of $4 \times (2 + 3)$.\n2. First, solve the expression inside the parentheses: $2 + 3 = 5$.\n3. Then multiply the result by 4: $4 \times 5 =

1. Let's start by stating the problem: evaluate the expression $4 \times (2 \ 3)$. 2. The operator between 2 and 3 is missing or unclear; it could be addition, subtraction, multipl

1. Let's evaluate the expression $4.000-36$ carefully. 2. Note that $4.000$ is equivalent to the number $4$ (the trailing zeros after the decimal point do not change the value).

1. We are asked to simplify the expression $20 \div 10 \div 3$. 2. Division is performed from left to right.

1. Stated problem: Evaluate the expression $4.000 - 36$. 2. Explanation: Here, we subtract 36 from 4.000 (which is the same as 4).
