Question

2 5 3 = 30

Insert operation signs to make each equation true.

a) 2 + 5 x 3 = 30
b) 2 x 5 + 3 = 30
c) 2 x (5 + 3) = 30
d) (2 x 5) + 3 = 30

Answer 1

To make the equation 2 5 3 = 30 true, we need to insert operation signs between the numbers. The correct equation is 2 + 5 x 3 = 30.

Step-by-step explanation:

To make the equation 2 5 3 = 30 true, we need to insert operation signs between the numbers. Let's go through each option:

a) 2 + 5 x 3 = 30 - This equation is true because 5 x 3 = 15, and 2 + 15 = 30.

b) 2 x 5 + 3 = 30 - This equation is true because 2 x 5 = 10, and 10 + 3 = 13.

c) 2 x (5 + 3) = 30 - This equation is true because 5 + 3 = 8, and 2 x 8 = 16.

d) (2 x 5) + 3 = 30 - This equation is true because 2 x 5 = 10, and 10 + 3 = 13.

So, the correct answer is option a) 2 + 5 x 3 = 30.
