Answer 2

а) 245 + 35 * 18: To solve this expression, we need to follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). In this case, we have multiplication and addition.

First, we need to multiply 35 by 18, which equals 630. Then, we add 245 to the result: 630 + 245 = 875.

The result of 245 + 35 * 18 is 875.

б) (87 + 35) * 25: Again, we need to follow the order of operations. In this case, we have parentheses and multiplication.

Inside the parentheses, we add 87 and 35, which equals 122. Then, we multiply 122 by 25: 122 * 25 = 3050.

The result of (87 + 35) * 25 is 3050.

д) 10260 : 36 + 164: Following the order of operations, we have division and addition.

First, we divide 10260 by 36, which equals 285. Then, we add 164 to the result: 285 + 164 = 449.

The result of 10260 : 36 + 164 is 449.

г) 52998 : (37 + 29): Again, following the order of operations, we have parentheses and division.

Inside the parentheses, we add 37 and 29, which equals 66. Then, we divide 52998 by 66: 52998 : 66 = 803.

The result of 52998 : (37 + 29) is 803.

So, to summarize: а) 245 + 35 * 18 = 875 б) (87 + 35) * 25 = 3050 д) 10260 : 36 + 164 = 449 г) 52998 : (37 + 29) = 803
