Let's use a similar strategy to add 58 + 92.

  1. First, break down each number into tens and ones:

    • 58 has 5 tens and 8 ones.
    • 92 has 9 tens and 2 ones.
  2. Now, let's add the ones first:

    • I know that 8 and 2 make 10 (or 1 ten).
  3. Next, we can combine the tens:

    • I have 5 tens from 58 and 9 tens from 92, which makes 14 tens.
    • Since I added 10 from the ones, this means I have 1 ten from the 10 we made, combining it with the 14 tens.
  4. Finally, let's put it together:

    • 14 tens and 1 ten equals 15 tens, which is 150.

So, 58 + 92 = 150.
