Evaluate the expression.

m×n
, when m=13
and n=12

156

To evaluate the expression m × n, when m = 13 and n = 12, we simply substitute the given values into the expression.

m × n = 13 × 12

Now, we can multiply these two numbers.

13 × 12 = 156

Therefore, the value of the expression m × n, when m = 13 and n = 12, is 156.
