Question

(826 826:826 + 205.308):49 - 2350: 23568 - (430 - 80 - 138 600:45): 870​

Answer 1

(826826 : 826 + 205308):49-2350:235=

1) 826826:826= 1001

2) 1001+205308 = 206309

3) 206309 : 49 = 4210, 38

4) 2350:235= 10

5) 4210, 38 - 10 = 4200, 38

68 - (430-80-138000:45):870=

1) 138000×45 = 6210000

2) 430+80+6210000 = 6210510

3) 68- 6210510 = 6210442

4) 6210442 : 870 = 7138, 43908

Answer 2

Let's break down the expression and solve it step by step using the order of operations (also known as PEMDAS):

1. First, we perform any operations inside parentheses:

   • (430 - 80 - 138 600:45) = (430 - 80 - 308) = 42

2. Next, we perform any multiplication or division, working from left to right:

   • 23568 / 42 = 561.14
   • 205.308 / 49 = 4.19012

3. Then, we perform any addition or subtraction, working from left to right:

   • 826 + 4.19012 = 830.19012
   • 830.19012 - 561.14 = 269.05012

4. So the final answer is approximately 269.05012.
