MULTIPLICATION: MULTIPLICATION BY: ABHA ARORA
MULTIPLICATION: MULTIPLICATION It means repeated addition EXAMPLE : 7 X 2 = 7 + 7 3X 6 = 3 + 3 + 3 + 3 + 3 + 3
Multiplying by 7: Multiplying by 7 7 x 1 means there is one group of 7 7 x 2 means there are two groups of 7 7 x 3 means there are three groups of 7
LETS BUILD THE TABLE OF 7: LETS BUILD THE TABLE OF 7 7 X 1 = IT SHOWS 7 X 1 = 7
7 X 2 =: 7 X 2 = IT SHOWS 7 X 2 = 14
7 X 3 =: 7 X 3 = IT SHOWS 7 X 3 = 21
7 X 3 =: 7 X 3 = IT SHOWS 7 X 4 = 28
7 X 5 =: 7 X 5 = IT SHOWS 7 X 5 = 35
TABLE OF 7: TABLE OF 7 7 X 1 = 7 7 X 2 = 14 7 X 3 = 21 7 X 4 = 28 7 X 5 = 35 7 X 6 = 42 7 X 7 = 49 7 X 8 = 56 7 X 9 = 63 7 X 10 = 70
SIMILARLY TABLE OF 8: SIMILARLY TABLE OF 8 8 X 1 means 1 group of 8 8 x 2 means 2 group of 8 8 x 3 means 3 group of 8 and so on….
8 x 1 =: 8 x 1 = IT SHOWS 8 X 1 = 8
8 X 2 =: 8 X 2 = IT SHOWS 8 X 2 = 16
8 X 3 =: 8 X 3 = IT SHOWS 8 X 3 =24
8 X 4 =: 8 X 4 = IT SHOWS 8 X 4 = 32
LETS CONCLUDE THEN :: LETS CONCLUDE THEN : 8 X 1 = 8 (10 -2 ) 8 X 2 = 16 ( 20 – 4 ) 8 X 3 = 24 ( 30 – 6 ) 8 X 4 = 32 ( 40 – 8 ) 8 X 5 = 40 ( 50 – 10 ) 8 X 6 = 48 ( 60 – 12 ) 8 X 7 = 56 ( 70 – 14 )
Slide 16: 8 X 8 = 64 ( 80 – 16 ) 8 X 9 = 72 ( 90 – 18 ) 8 X 10 = 80 ( 100 – 20 )
TABLE OF 9: TABLE OF 9 9 x 1 means 1 group of 9 9x 2 means 2 group of 9 9x3 means 3 groups of 9 and so on……….
9 x 1: 9 x 1 IT SHOWS 9 X 1 = 9
9 X 2: 9 X 2 IT SHOWS 9 X 2 = 18
9 X 3: 9 X 3 IT SHOWS 9 X 3 = 27
9 X 4: 9 X 4 IT SHOWS 9 X 4 = 36
9 X 5: 9 X 5 IT SHOWS 9 X 5 = 45
TABLE OF 9: TABLE OF 9 9 X 1 = 9 9 X 2 = 18 ( 1 + 8 = 9 ) 9 X 3 = 27 ( 2 + 7 = 9 ) 9 X 4 = 36 ( 3 + 6 = 9 ) 9 X 5 = 45 ( 4 + 5 = 9 ) 9 X 6 = 54 ( 5 + 4 = 9 ) 9 X 7 = 63 ( 6 + 3 = 9) 9 X 8 = 72 ( 7 + 2 = 9) 9 X 9 = 81 ( 8 + 1 = 9 ) 9 X 10= 90 ( 9 + 0 = 9 )
