LINEAR SUBTRACTION
Q.1) 26 Ones - 12 Ones = ?
26 Ones - 12 Ones
= 2 Tens + 6 Ones - 1 Ten - 2 Ones Step.1 – Sub ‘Ones’
= 2 Tens - 1 Ten + 6 Ones - 2 Ones
= 2 Tens – 1 Ten + 4 Ones Step.2 – Sub ‘Tens’
= 1 Ten + 4 Ones = 14 (Ans.)
Q.2) 49 Ones - 32 Ones = ?
49 Ones - 32 Ones
= 4 Tens + 9 Ones - 3 Tens - 2 Ones Step.1 – Sub ‘Ones’
= 4 Tens - 3 Tens + 9 Ones - 2 Ones
= 4 Ten – 3 Tens + 7 Ones Step.2 – Sub ‘Tens’
= 1 Ten + 7 Ones = 17 (Ans.)
Q.3) 48 Ones - 23 Ones = ?
48 Ones - 23 Ones
= 4 Tens + 8 Ones - 2 Tens - 3 Ones Step.1 – Sub ‘Ones’
= 4 Tens - 2 Tens + 8 Ones - 3 Ones
= 4 Tens – 2 Tens + 5 Ones Step.2 – Sub ‘Tens’
= 2 Tens + 5 Ones = 25 (Ans.)
Q.4) 75 Ones - 42 Ones = ?
75 Ones - 42 Ones
= 7 Tens + 5 Ones - 4 Tens - 2 Ones Step.1 – Sub ‘Ones’
= 7 Tens - 4 Tens + 5 Ones - 2 Ones
= 7 Tens – 4 Tens + 3 Ones Step.2 – Sub ‘Tens’
= 3 Tens + 3 Ones = 33 (Ans.)
Q.5) 36 Ones - 4 Ones = ?
36 Ones - 4 Ones
= 3 Tens + 6 Ones - 0 Tens - 4 Ones Step.1 – Sub ‘Ones’
= 3 Tens - 0 Tens + 6 Ones - 4 Ones
= 3 Tens – 0 Ten + 2 Ones Step.2 – Sub ‘Tens’
= 3 Tens + 2 Ones = 32 (Ans.)
