Drag the tiles to the boxes to form correct pairs,
match the pairs of equivalent expressions
(a + 21) – (1 +26
85–15
46 + 2
(36 – 3) – (8 + 66)
(5 + 26) + (21 +)
- 11
(-10+b)+(76-5)
- 15
- 26

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
