100 – 10 × 1000 ÷ 1000 + 100 × 10

Since, 20×10=200, therefore, – means ×.
8+4=12, therefore, ÷ means +.
6–2=4, therefore, × means –.
and 12÷3=4, therefore, + means ÷.

Now, given expression
100 – 10 × 1000 ÷ 1000 + 100 × 10

Using the correct symbols, we have:
= 100 × 10 – 1000 + 1000 ÷ 100 – 10

If 3+5=16, 7+9=64, 10+12=121; then what will be the value of ‘11+3’?

The rule is:
a + b = mathematical-operations-21668.png
3 + 5 = mathematical-operations-21661.png etc.
∴ 11 + 3 = mathematical-operations-21655.png = 49

If 36×92=9623, 25×82=8522, 68×75=7856; then what will be the value of ‘47×52’?

The rule is the digits are jumbled in an order.

If P = 6, J = 4, L = 8, M = 24; then what will be the value of the following expression?

M × J ÷ L + J

M × J ÷ L + J
24 × 4 ÷ 8 + 4
= 24 × ½ + 4
= 12 + 4 = 16
