Answer 1

532 * ( 150462 - 149748 ) - ( 784689 - 781543 ) = 532 * 714 - ( 784689 - 781543 ) = 532 * 714 - 3146 379848 - 3146 = 376 702; То есть получили, 532 * ( 150462 - 149748 ) - ( 784689 - 781543 ) = 376 702. б) 604 * 706 : 8 - ( 302000 - 39430 ) : ( 4960 : 80 ) * 12 = 604 * 706 : 8 - 262 570 : ( 4960 : 80 ) * 12 = 604 * 706 : 8 - 262 570 : 62 * 12 = 75.5 * 706 - 262 570 : 62 * 12 = 75.5 * 706 - 4 235 * 12 = 53 303 - 4 235 * 12 = 53 303 - 50 820 = 2 483 ; То есть получили, 604 * 706 : 8 - ( 302000 - 39430 ) : ( 4960 : 80 ) * 12 = 2 483.

Answer 2

Order of Operations and Calculations

To solve the given expressions, we need to follow the order of operations, which is commonly remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Let's solve the given expressions step by step:

1. (26230 + 86 * 206 + 2886 * 86) - 456 * 507 2. 832 * (150462 - 149748) - (784689 - 781543) 3. 604 * 706 / 8 - (302000 - 39430) + (4960 / 80) * 12 4. 300 * 3000 - 907788 / (98 * 29 - 132370 / 62) * 87

Step 1: Solving the First Expression

Let's solve the first expression step by step:

1. 26230 + 86 * 206 = 26230 + 17716 = 43946 2. 2886 * 86 = 247896 3. 43946 + 247896 = 291842 4. 291842 - 456 * 507 = 291842 - 231192 = 60650

So, the value of the first expression is 60650.

Step 2: Solving the Second Expression

Now, let's solve the second expression:

1. 150462 - 149748 = 714 2. 832 * 714 = 594048 3. 784689 - 781543 = 3146 4. 594048 - 3146 = 590902

The value of the second expression is 590902.

Step 3: Solving the Third Expression

Moving on to the third expression:

1. 604 * 706 = 426424 2. 302000 - 39430 = 262570 3. 4960 / 80 = 62 4. 62 * 12 = 744 5. 426424 / 8 - 262570 + 744 = 53278

The value of the third expression is 53278.

Step 4: Solving the Fourth Expression

Finally, let's solve the fourth expression:

1. 98 * 29 = 2842 2. 132370 / 62 = 2135 3. 2842 - 2135 = 707 4. 907788 / 707 * 87 = 111732

The value of the fourth expression is 111732.

Therefore, the values of the given expressions are: 1. 60650 2. 590902 3. 53278 4. 111732
