Real problems from the practice worksheets, solved one step at a time.

1. Example 1

   6 × 6 + 3 = ?

   1. Multiply before you add or subtract: 6 × 6 = 36, so now you have 36 + 3.
   2. Add: 36 + 3 = 39.
   3. So 6 × 6 + 3 = 39.

   Answer: 39

2. Example 2

   5 × 6 − 3 = ?

   1. Multiply before you add or subtract: 5 × 6 = 30, so now you have 30 − 3.
   2. Subtract: 30 − 3 = 27.
   3. So 5 × 6 − 3 = 27.

   Answer: 27

3. Example 3

   1 + 4 × 7 = ?

   1. Multiply before you add or subtract: 4 × 7 = 28, so now you have 1 + 28.
   2. Add: 1 + 28 = 29.
   3. So 1 + 4 × 7 = 29.
