The first (left most) digit is the number of tens and the other is the number of ones. So 57 = 5 tens plus 7 ones = 50 + 7 = 57
well 7 tens is 70 and 8 tens is 80 and the number containts 4 ones so it would be 74.
So far, you know that your number has a seven in the tens column:7?The ones digit is one more than the tens digit, which is 7.7+1=8Your number is 78.

84
well 7 tens is 70 and 8 tens is 80 and the number containts 4 ones so it would be 74.
3 tens is equal to the number 30, and 3 ones is equal to the number 3.So, 3 tens and 3 ones is 33; and 67 minus 33 (or 67 less33) is 34.You could also look at the number 67 and see that it is 6 tens and 7 ones. Then it is easier to say "6 tens and 7 ones minus 3 tens and 3 ones = 34"because:6 tens minus 3 tens = 3 tens, and 7 ones minus 3 ones = four ones.3 tens and four ones = 34
427 = 42 tens, plus 7 ones
7 tens and 20 ones is 7 × 10 + 20 × 1 = 70 + 20 = 90 (ninety).
So far, you know that your number has a seven in the tens column:7?The ones digit is one more than the tens digit, which is 7.7+1=8Your number is 78.
