Erro ao utilizar um modulo.

Boa tarde pessoal…preciso da ajuda de voces. 

Estou criando um modulo no npm para utilização em projetos. Fiz um modulo bem simples de uma calculadora em TypeScript. Gero o pacote e publico depois. Quando vou utilizar no meu projeto nao reconhece. Acredito que falta algum detalhe.

Codigo para criação do pacote no NPM

CalculadoraModule.ts

import { Calculadora } from './calculadora';
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';


@NgModule({
    imports: [CommonModule],
    declarations: [Calculadora],
    exports: [Calculadora],
    entryComponents: [Calculadora],
})
export class CalculadoraModule { }

Calculadora.ts

import { Component } from '@angular/core';

@Component({
    selector: 'Calculadora'
})
export class Calculadora {
    constructor() {

    }

    somar(a: number, b: number) {
        return a + b;
    }

    subtrair(a: number, b: number) {
        return a - b;
    }

    multiplicar(a: number, b: number) {
        return a * b;
    }

    dividir(a: number, b: number) {
        return a / b;
    }
}
