1. You could break them up:
10+30+20+10=70
6+5+4+4=19
70+19=89

2. Separate to groups:
16+35=51
24+14=38
51+38=89

Additions strategies assist children in learning number relationships and comprehending why quantities connect. When kindergartners were allowed to regularly answer addition problems that enhanced skills provide a framework for understanding mathematics at the elementary level.

Given:

[tex]\bold{16+35+24+14}[/tex]

To find:

Adding value in two different strategies.

Solution:

First strategy:

[tex]\to \bold{16+35+24+14= 89}[/tex]

Second strategy:

Separate the value into two parts then add the value:

[tex]\to \bold{(16+35)+(24+14)= (51)+(38)= 51+38= 89}[/tex]

Third strategy:

add first and the last term then adds mid-two-term:

[tex]\to \bold{(16+14) +(35+24)=(30)+(59)=30+59= 89}[/tex]
