Abstract：In the literature, we will briefly explain the great mathematical knowledge system, to the best of our knowledge. Ulam is We investigate the Hyers–Ulam stability of an equation involving a single variable and it preserves the addition operation, besides other certain conditions. The theory is employed and stability theorems are proven for various functional equations involving several variables. By comparing this method with the available techniques, it was noticed that this method does not require any restriction on the parity, on the domain, and on the range of the function. Our findings suggest that it is very much easy and more appropriate to apply the proposed method while investigating the stability of functional equations, in particular for several variables.
