Question 2 (Integers)[13] Calculate the following without the use of a calculato \( 2.1 .1-7-(-3)+(-2) \)

To solve the expression \( 2.1 .1 - 7 - (-3) + (-2) \), we'll break it down step-by-step. First, simplify each part: 1. Start with \( 2.1 .1 \), which seems to be a typo. If we consider it as simply \( 2.1 \), we continue. 2. Now, calculate: \( 2.1 - 7 \) gives us \( 2.1 - 7 = -4.9 \). 3. Next, subtracting a negative number: \( -4.9 - (-3) \) is the same as \( -4.9 + 3 = -1.9 \). 4. Finally, add \( (-2) \): \( -1.9 - 2 = -3.9 \). So, the result is \( -3.9 \). Want to impress your friends with how fractions and decimals work? Here’s a tip: converting everything to fractions first can sometimes clear away confusion. For example, \( 2.1 \) is \( \frac{21}{10} \). When you manage mixed operations, it can help keep your calculations precise, especially with negative numbers. And if you find long calculations tiresome, consider looking into mental math strategies! Tricks like breaking down complex constants (like 7) into smaller numbers or using complements can expedite your math processes. Just a little creativity can make solving calculations not only faster but more fun!
