Wiley Edge Mathematical Order Quiz-1

From option (1), 96 ÷ 12 + 24 - 32 = 0
LHS = 96/12 + 24 - 32
= 8 + 24 - 32 = 32 -32 = 0
LHS = RHS

Using the correct symbols, we have:
Given expression = 26 ÷ 2 + 3 × 6 – 4 = 13 + 18 – 4 = 27

Given, 6 - 10 + 16 = 0
On interchanging signs '+' and '-' and number 6 and 10 in option (a), we get
10 + 6 - 16 = 0
16 - 16 = 0
0 = 0, which is true

As, 541 x 125 = (5+4+1) + (1+2+5) = 18
418 x 116 = (4+1+8) + (1+1+6) = 21
and 891 x 455 = (8+9+1) + (4+5+5) = 32
Similarly, 694 x 748 = (6+9+4) + (7+4+8) = 38

Using the correct symbols, we have:
Given expression = (4 × 15 + 12) ÷ 8 – 9 = 72 ÷ 8 – 9 = 9 – 9 = 0

Using the correct symbols, we have :
Given expression = (20 * 5) + (7 *4) - (15*3)= 83

Using the correct symbols, we have:
Given expression
65 K 5 Q 8 J 6 T 12 = ?
= 65 ÷ 5 + 8 × 6 – 12
= 13 + 48 – 12
= 61 - 12 = 49

Using the proper notations in (d), we get the statement as:
12 – 40 + 24 × 12 ÷ 2
= 12 – 40 + 24 * 6
= 12 - 40 + 144
= 156 - 40 = 116

(20 × 18) + 9 - 36 = 326
By interchanging,
(20 - 18) + 9 × 36 = 326
2 + 9 * 36 = 326
2 + 324 = 326

108 – 12 × 10 ÷ 9 = 81
Putting (– & ÷) in the equation,
⇒ 108 ÷ 12 × 10 – 9 = 81
⇒ 9 × 10 – 9 = 81
⇒ 90 – 9 = 81
