Answer 1

Ответ:

(1000-815):5+12×60=757

1000-815=185

185÷5=37

12×60=720

37+720=757

400-18×11+249=451

-18×11=-198

400-198=202

202+249=451

Answer 2

Ответ:757

Пошаговое объяснение: 100-815=185:5=35

12*60=720

Answer 3

To calculate the expressions, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). Here are the calculations step by step:

1. (1000 - 815) / 5 + 12 * 60 First, solve the subtraction inside the parentheses: (1000 - 815) / 5 + 12 * 60 185 / 5 + 12 * 60

   Then, perform the division and multiplication from left to right: 37 + 720

   Finally, add the two results: 37 + 720 = 757

So, (1000 - 815) / 5 + 12 * 60 equals 757.

2. 400 - 18 * 11 + 249 Perform the multiplication and subtraction from left to right: 400 - 198 + 249

   Now, perform the remaining subtraction and addition: 400 - 198 + 249 = 251

So, 400 - 18 * 11 + 249 equals 251.
