Describe the mental math steps you would use to find 7(42)

Sagot :

You would find 7*40    7*4=28
So 7*40=280 (just add a zero)
7*2=14
The answer would be 280+14=294

Answer:

[tex]7\times 42 = 294[/tex]

Step-by-step explanation:

Distributive property of multiplication over addition:

When a number is multiplied to a sum of two numbers then it can be multiplied to the numbers individually and then add the two products,

It can be written as:

[tex]a\times (b+c) = (a\times b) + (a\times c)[/tex]

Similarly, we can use this property to find the product of [tex]7\times 42[/tex]

[tex]7\times 42\\= 7\times (40+2)\\= (7\times 40) + (7\times 2)\\= 280 + 14\\= 294[/tex]

The product of 7 and 42 is 294.
