Question

e (-6 + 17) - 20 =
a (-64 ÷ 2) ÷ -2 =
b (-5 - -6) · -87 =
t (-40 + -50) ÷ 9 =
r (-13 · -2) + -12 =
n (42 ÷ -7) - 6 =
d (-5 - -30) (3) =
l (-12 + -18) ÷ -15 =
t (-8 · -8) - -8 =

Explanation:

Step1: Calculate E: Solve parentheses first

$(-6 + 17) - 20 = 11 - 20$

Step2: Finalize E: Subtract

$11 - 20 = -9$

Step1: Calculate A: Solve inner division

$(-64 \div 2) \div -2 = -32 \div -2$

Step2: Finalize A: Divide

$-32 \div -2 = 16$
---

Step1: Calculate B: Solve parentheses first

$(-5 - -6) \cdot -87 = (-5 + 6) \cdot -87 = 1 \cdot -87$

Step2: Finalize B: Multiply

$1 \cdot -87 = -87$

Step1: Calculate T: Solve parentheses first

$(-40 + -50) \div 9 = -90 \div 9$

Step2: Finalize T: Divide

$-90 \div 9 = -10$
---

Step1: Calculate R: Solve multiplication first

$(-13 \cdot -2) + -12 = 26 + -12$

Step2: Finalize R: Add

$26 + -12 = 14$
---

Step1: Calculate N: Solve division first

$(42 \div -7) - 6 = -6 - 6$

Step2: Finalize N: Subtract

$-6 - 6 = -12$
---

Step1: Calculate D: Solve parentheses first

$(-5 - -30)(3) = (-5 + 30)(3) = 25 \cdot 3$

Step2: Finalize D: Multiply

$25 \cdot 3 = 75$
---

Step1: Calculate L: Solve parentheses first

$(-12 + -18) \div -15 = -30 \div -15$

Step2: Finalize L: Divide

$-30 \div -15 = 2$
---

Step1: Calculate T: Solve multiplication first

$(-8 \cdot -8) - -8 = 64 + 8$

Step2: Finalize T: Add

$64 + 8 = 72$

Answer:

E: $-9$
A: $16$
B: $-87$
T: $-10$
R: $14$
N: $-12$
D: $75$
L: $2$
T: $72$
