Answer 1

The value of the expressions are

1. = 2

2. = 8

3 = 3 ⅓

4 = -1/2

5 = 1 ⅕

In mathematics, expressions are combinations of numbers, variables, and operators (like +, -, *, /). They represent mathematical relationships and can be as simple as 3x or complex like (2a + 5) / (3b - 1).

Solving the numerator;

-7 + 2² -5

= -7 + 4 -5

= -8

Solving the denominator;

-5+3-2 = -4

therefore, (-7+2²-5)/-5+3-2 = -8/-4

= 2.

2. -8+ ( -8+4)²

= -8 +(-4)²

= -8 +16

= 8

3. -3/4 ÷ -9/16 + 3

= 3/4 × 16/9 + 3

= 4/3 + 3

= 10/3 = 3 ⅓

4. -6 +4)/-1 +5

= -2/4 = -1/2

5. 8- ( 5+(-12)/18

= 8 -(-7)/8

= 15/18 = 5/6 = 1 ⅕

Answer 2

1. -8/ -4

2. 44

3. 577/192

4. -2/4

5. -7/18

Hope this Helps!
