1

Understand the problem

(10+5+18)×4= (10+5+18)\times4=

2

Step-by-step solution

We will use the distributive property and multiply each term in parentheses by 4:

4×18+4×5+4×10= 4\times18+4\times5+4\times10=

We will solve the exercise from left to right.

We will solve the first multiplication exercise vertically. We will make sure to write correctly and multiply ones by ones, and ones by tens as follows:

4×18 4\\\times18

We get the result: 72.

Let's solve the remaining multiplication exercises:

4×5=20 4\times5=20

4×10=40 4\times10=40

Now we'll connect all the results in the following way:

72+20+40= 72+20+40=

We will solve the exercise vertically, making sure to write correctly and add ones with ones and tens with tens, as follows:

72+2040 72\\+20\\40

We'll add all the ones together and get: 2

We'll add all the tens together and get: 13

Therefore, we got the number:

132 132
