I want the properties involved in each:-

1. 15 + 34 = 34 + 15
2. 738 x 1 = 738
3. 4 x 85 = 85 x 4
4. 94 x 0 = 0
5. (71+26) + 53 = 71 + (26 + 53)
6. (294 x 3) x 5 294 x (3 x 5)
7. 79 x 0 = 0
8. 28 + 53 +72 = 53 + 100
9.5 x 303 x 4 = 303 x 20
80 x 10 = 10 = 80

Answer 1

Answer:

Answer:

(a) 738 × 103

= 738 × (100 + 3)

= 738 × 100 + 738 × 3

= 73800 + 2214

= 76014

(b) 854 × 102

= 854 × (100 + 2)

= 854 × 100 + 854 × 2

= 85400 + 1708

= 87108

(c) 258 × 1008

= 258 × (1000 + 8)

= 258 × 1000 + 258 × 8

= 258000 + 2064

= 260064

(d) 1005 × 168

= (1000 + 5) × 168

= 1000 × 168 + 5 × 168

= 168000 + 840
