Answer :
Let's break down and solve each of the expressions given in the table step by step:
1. First row:
- [tex]\( 7 - 8 \)[/tex]
- [tex]\( -4 - 5 \)[/tex]
Solutions:
- [tex]\(7 - 8 = -1\)[/tex]
- [tex]\(-4 - 5 = -9\)[/tex]
2. Second row:
- [tex]\(-2 \times (-2)\)[/tex]
- [tex]\(9 \times (-1)\)[/tex]
Solutions:
- [tex]\(-2 \times (-2) = 4\)[/tex]
- [tex]\(9 \times (-1) = -9\)[/tex]
3. Third row:
- [tex]\(-49 \div (-7)\)[/tex]
- [tex]\(-56 \div 7\)[/tex]
Solutions:
- [tex]\(-49 \div (-7) = 7\)[/tex]
- [tex]\(-56 \div 7 = -8\)[/tex]
4. Fourth row:
- [tex]\(-3 + 7\)[/tex]
- [tex]\(-3 + (-7)\)[/tex]
Solutions:
- [tex]\(-3 + 7 = 4\)[/tex]
- [tex]\(-3 + (-7) = -10\)[/tex]
5. Fifth row:
- [tex]\(-8 - (-8)\)[/tex]
- [tex]\(2 - 13\)[/tex]
Solutions:
- [tex]\(-8 - (-8) = 0\)[/tex]
- [tex]\(2 - 13 = -11\)[/tex]
6. Sixth row:
- [tex]\(-1 \times 1\)[/tex]
- [tex]\(-2 \times 6\)[/tex]
Solutions:
- [tex]\(-1 \times 1 = -1\)[/tex]
- [tex]\(-2 \times 6 = -12\)[/tex]
7. Seventh row:
- [tex]\(12 \div (-4)\)[/tex]
- [tex]\(-84 \div 7\)[/tex]
Solutions:
- [tex]\(12 \div (-4) = -3\)[/tex]
- [tex]\(-84 \div 7 = -12\)[/tex]
Compiling these results, we get the following list of solutions:
[tex]\[ [-1, -9, 4, -9, 7, -8, 4, -10, 0, -11, -1, -12, -3, -12] \][/tex]
