1. Problem type and necessary steps:
a) The problem is to find the sum of the series 1-2+3-4+5-6+...+2024-2024.
To solve this, we can use a loop to iterate through the numbers from 1 to 2024 and add or subtract them based on their position in the series.
b) The problem is to find the result of the expression 1-2.
This can be solved by subtracting 2 from 1.
c) The problem is to find the result of the expression 3-4.
This can be solved by subtracting 4 from 3.
d) The problem is to find the result of the expression (-3) - (-7) - 21.
This can be solved by subtracting -7 from -3 and then subtracting 21 from the result.
e) The problem is to find the result of the expression (-2) * (-3).
This can be solved by multiplying -2 and -3.
g) The problem is to find the result of the expression (-2) - (-3) * (-4).
This can be solved by multiplying -3 and -4, and then subtracting the result from -2.
h) The problem is to find the result of the expression (-2) * (-4) - 2.
This can be solved by multiplying -2 and -4, and then subtracting 2 from the result.
2. Full executable Python code:
a) Sum of the series 1-2+3-4+5-6+...+2024-2024:
sum = 0
for i in range(1, 2025):
if i % 2 == 0:
sum -= i
else:
sum += i
print("Sum of the series:", sum)
b) Result of the expression 1-2:
result = 1 - 2
print("Result:", result)
c) Result of the expression 3-4:
result = 3 - 4
print("Result:", result)
d) Result of the expression (-3) - (-7) - 21:
result = -3 - (-7) - 21
print("Result:", result)
e) Result of the expression (-2) * (-3):
result = -2 * -3
print("Result:", result)
g) Result of the expression (-2) - (-3) * (-4):
result = -2 - (-3) * (-4)
print("Result:", result)
h) Result of the expression (-2) * (-4) - 2:
result = -2 * -4 - 2
print("Result:", result)
