Question

2+2*9÷2-5+5-5×500÷100:1+2400-2399×500-999+12×500÷100+100×1000÷1000×900000=?

Answer 1

Объяснение:

2+9-5+5-25+2400-1199500-999+60+90000000=2386-1199500-939+90000000=

=1447-1199500+90000000=

= - 1198053+90000000=88801947

Answer 2

To solve this mathematical expression, we need to follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down the expression step by step:

$2 + 2 \times 9 \div 2 - 5 + 5 - 5 \times 500 \div 100 : 1 + 2400 - 2399 \times 500 - 999 + 12 \times 500 \div 100 + 100 \times \frac{1000}{1000} \times 900000$

1. $2 + 2 \times 9 \div 2 - 5 + 5 - 5 \times 500 \div 100 : 1$
   Evaluate multiplication and division first:
   $2 + 18 - 5 + 5 - 5 \times 5 : 1$

2. Continue with multiplication and division:
   $2 + 18 - 5 + 5 - 25$

3. Perform addition and subtraction:
   $20 - 25$

4. $2400 - 2399 \times 500 - 999 + 12 \times 500 \div 100 + 100 \times \frac{1000}{1000} \times 900000$
   Perform multiplication and division:
   $2400 - 1199500 - 999 + 60 + 100 \times 900000$

5. Continue with addition and subtraction:
   $-1195039 + 60 + 900000$

6. $100 \times \frac{1000}{1000} \times 900000$
   Simplify the expression:
   $100 \times 900000$

7. Add the results obtained in steps 5 and 6:
   $-1195039 + 60 + 900000$
   $-295979 + 900000$

Now, add the result from step 7 to the result from step 4:

$20 - 25 + (-295979 + 900000)$

Combine like terms:

$20 - 25 + 604021$

Finally, perform the remaining addition and subtraction:

$604021 - 5$

The answer is $604016$.
