Answer 2

Question

   2550 - [510 - {270 -  90 - (80 + 7)}]​

Step-by-step explanation:

• We solve the braces on the precedence order
• firstly we'll solve the values inside () round braces
• then we'll solve the values inside {} curly braces
• then we'll solve the values inside [] square braces
• 2550 - [510 - {270 - 90 - (80 + 7)}]​
• =2550 - [510 - {270 - 90 - 87}]
• =2550 - [510 - {270 - 177} =2550 - [510 - 93]
• =2550 - [417]
• =2133
