Answer 1

1)34+53=87
2)6351:87=73
3)6351-73=6218

1)66174:82=807
2)5986:73=82
3)807+82=889

Answer 2

1) To solve the expression 6351-6351:(34+53), we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

First, let's simplify the expression inside the parentheses: (34+53) = 87.

Next, perform the division: 6351 ÷ 87 = 73.

Finally, subtract 73 from 6351: 6351 - 73 = 6278.

Therefore, the value of the expression 6351-6351:(34+53) is 6278.

2) Now let's solve the expression 5986:73 + 66174:82.

Again, we'll follow the order of operations.

First, perform the division: 5986 ÷ 73 = 82.

Next, perform the division: 66174 ÷ 82 = 806.

Finally, add the results: 82 + 806 = 888.

Therefore, the value of the expression 5986:73 + 66174:82 is 888.
