Please answer question 20-23 only

Seriously, I suggest you ask your teacher for a sit-down together, to review some of the previous work. Math builds like brick wall. When there's a level that you don't understand, then you can't build more levels on top of it. You can't keep going through math getting answers from other people. Sooner or later, you need to understand how to solve the questions on your own, and the longer you put it off, the tougher it could get.
In these questions, " + " is always 3 more than 'a' is.
20). " + " is 3. That's 3 more than 'a'. So 'a' is zero.
21). 'a' is 1. " + " is 3 more than 'a'. So " + " is 4.
22). " + " is 5. That's 3 more than 'a'. So 'a' is 2.
23). 'a' is 3. " + " is 3 more than 'a', so " + " is 6.

The values of 'a' for questions 20 to 23 are 0, 1, 2, and 3 respectively. Each of these values is found by setting up an equation where ' + ' is equal to 'a + 3' and solving for 'a'. Thus, we deduce the answers step by step based on the definitions provided.
