Answer 1

Answer: 356

Explanation:

-start by grouping numbers into smaller portions (ex. the 5x5)

-5x5=25

-4x3=12

-Now we have 25x12.

-10x25=250, now add two more 25's

-250+50=300 or 25x12=300

-Add 56 to get 356

Answer 2

`\fbox{356}`

`(5*4*5*3)+56`

`5*4=20\\5*3=15\\20*15=300`

`300+56=356`
