Hi Furat,
You can calculate the number of operations manually.
Number of operations = O(Batch_size * Σ (weights+bias) * sizeofdatatype)
Number of memory operations is a function of batch_size (the number of inputs given to the MLP), weights and bias (Each neuron connection is given a weight, depending on the number of layers and neurons in each layer, you can calculate weights and bias), and sizeofdatatype (depending on the input, the data type for each weight and bias is also defined).
However, If memory limitations are a problem, the amount of temporary storage needed can be reduced by a factor of N. You can refer to the link here.
