Combine multiplicatcation and addition by multiplying each addend by the number and adding the products?

To combine multiplication and addition, you can apply the distributive property. This means that if you have a number multiplied by a sum, you can multiply each addend by that number and then add the results together. For example, if you have ( a \times (b + c) ), it can be expressed as ( (a \times b) + (a \times c) ). This method simplifies calculations and demonstrates the relationship between addition and multiplication.
